9. y = -5x + 1
10. y + 1 = -2(x - 2)
11. y - 1 = 2/3(x - 3)
How to Write the Equation of a Line?For any given line, the equation that represents the line can be written as:
y = mx + b, in slope-intercept form, where m is the slope and b is the y-intercept of the line.y - b = m(x - a), in point-slope form, where m is the slope and (a, b) is a point on the line.5. Substitute m = -3, and (a, b) = (1, 5) into y - b = m(x - a):
y - 5 = -3(x - 1) [equation in point-slope form]
6. Substitute m = 2, and (a, b) = (-4, 3) into y - b = m(x - a):
y - 3 = 2(x - (-4))

A point that lies in the middle of a line and is equally spaced from its ends is the line's midway. The formula for the line's midpoint is [(x)1 + (x)2]/2, [(y)1 + (y)2]/2 if the line's endpoints are (x)1, (y)1, and (x), (y), respectively.
Explain about the midpoint?Using the equations [(x)1 + (x)2]/2, [(y)1 + (y)2]/2, one may get the midway. Here, the coordinates of two points are (x), (y), (x)2, (y)2, and the midway is a location that is equally spaced from both of these positions.
The exact middle number between two numbers is referred to as the midway. The midpoint calculation is the same as the two-number average calculation. Therefore, by adding any two numbers together and dividing by two, you may find the halfway between any two integers.
The distance formula, which is derived from the Pythagorean Theorem, is employed to determine the separation between two points in the plane. The Pythagorean Theorem is based on a right triangle where the angles are a and b.

determine whether the side lengths form a right triangle just say yes or no
Answer:
Yes, the side lengths
Explanation:
To be able to determine if the given side lengths of the triangle will form a right triangle, we'll have to apply the Pythagorean Theorem which states, in a right-angled triangle, the square of the hypotenuse(the longest side) must be equal to the sum of squares of the other two sides.
So let's go ahead and confirm;
[tex]\begin{gathered} 14.5^2=10.5^2+10^2 \\ 210.25=110.25+100 \\ 210.25=210.25 \end{gathered}[/tex]Since the Pythagorean theorem is obeyed as we can see above, then the side lengths will form a right triangle.

What type of linear equation is X +1 equals X +1?
It depicts horizontal linear equation, as the slope is 0.
The slope of horizontal lines is zero. Consequently, m = 0 in the slope-intercept equation y = mx + b. Y = b, where b is the y-coordinate of the y-intercept, results in the equation.
The y-coordinate of every point on a horizontal line is the same. The line's equation is y=b if two points share the same y coordinate, b. The point (0,b) is the y-intercept of the horizontal line y=b. Horizontal lines don't have an x -intercept other than the line y=0.
A horizontal line is a line that is perpendicular to the x-axis. Because the value of x never changes, the graph of a relation of the form x = 5 is a line parallel to the y-axis.

Jeremy and Justine work for a company that receives $45 for each unit of output sold. The company has a variable cost of $25 per item and a fixed cost of $1600.
Based on this information, Jeremy and Justine make some projections about potential profit.
Jeremy states that for every 100 units of output sold, the company will make $3,600 in profit.
Justine states that for every 300 units of output sold, the company will make $4,400 in profit.
Part A
Determine a function that models the profit for the company based upon the conditions for revenue and expense.
Part B
Are the claims about profit that Jeremy and Justine made true? Explain why Jeremy and Justine are each correct or incorrect and justify your reasoning.
The function for profit given the conditions for revenue and expense is P = $20a - $1,600.
The first claim is incorrect because profit is $400
The first claim is incorrect because profit is $4,400.
What is the profit?Profit is revenue less total cost. Total cost consists of fixed cost and variable cost. Fixed cost is the cost that does not change with the level of output. Variable cost is the cost that changes with output. It increases as the level of output increases. Revenue is output multiplied by price per unit.
Profit = revenue - total cost cost
Profit = (price x output) - fixed cost - variable cost
P = ($45 x a) - $1,600 - ($25 x a)
P = $45a - $1,600 - $25a
P = $20a - $1,600
Where:
P = profit
a = output
Profit when 100 units is sold:
P = (20 x 100) - $1,600
$2,000 - $1,600 = $400
Profit when 300 units are sold
P = (300 x 20) - $1600

The attached figure shows the location of P' and R' in the figure, after the dilation
What is dilation?Dilation involves enlarging or reducing the side length of a shape to create another shape by a constant scale factor, where the scale factor does not equal one.
How to determine the location of P' and R' in the figure?The figure that completes the question is added as an attachment
From the figure, we have the following parameters
Center of dilation = Point CLength CR = 2.6 unitsLength PR = 5 unitsScale factor of dilation = 3The image of dilation using the above parameters is the scaled factor of the given figure
As a general rule, the following are the properties of a scaled copy of another figure
If the scale factor is greater than 1, the side lengths would be greater than the original figureIf the scale factor is less than 1, the side lengths would be less than the original figureThe angles of both figures are the sameThe side lengths may or may not be whole numbersThe above means that
New lengths = Old lengths * Scale factor
So, we have
P'R' = PR * Scale factor
C'R' = CR * Scale factor
This gives
P'R' = 5 * 3
P'R' = 15
C'R' = 2.6 * 3
C'R' = 7.8

Use the graph to evaluate the expressions below.
f(2) = 3
f⁻¹(2) = 1
f⁻¹(0) = -1
(f⁻¹o f)(1) = 1
The graph of f(x) is given. Here, f(x) = y and f⁻¹(y) = x.
That is, f(x) are y values corresponding to the given x-values and f⁻¹(y) is the x-value corresponding to the given y-value.
From the graph, f(2) is the y value when x = 2.
So, f(2) = 3
Now f⁻¹(2) is the x-value when y = 2.
So, f⁻¹(2) = 1
Also f⁻¹(0) =-1
Since f(1) = 2,
(f⁻¹o f)(1) = f⁻¹(f(1)) = f⁻¹(2) = 1

Suppose that the functions h and g are defined as follows.
h(x) = (x+5)(x+5)
g(x) = 4x+5
h
¹(²)(-1).
(a) Find
h
(b) Find all values that are NOT in the domain of
g
If there is more than one value, separate them with commas.
For the given functions, we have that:
a) The numeric value of the division function at x = 4 is of (h/g)(4) = 81/21 = 3.86.
b) The value that is not in the domain of the division function is of x = -1.25.
Division functionIn this problem, the functions that we are given are defined as follows:
h(x) = (x + 5)(x + 5).g(x) = 4x + 5.To find the quotient function of h(x) and g(x), we just divide the function h(x) by the function g(x), that is:
h(x)/g(x) = [(x + 5)(x + 5)]/(4x + 5).
At x = 4, the numeric value is found replacing each instante of x by 4, hence:
(h/g)(4) = [(4 + 5)(4 + 5)]/(4(4) + 5)) = 81/21 = 3.86.
The denominator of a fraction cannot be zero, as division by zero does not exist, hence the value of x that is not on the domain of the division function is found as follows:
4x + 5 = 0.
4x = -5.
x = -5/4
x = -1.25.

What is basic algebra ?Mathematical expressions can be used to depict situations or issues, and algebra is the field of mathematics that does this. For a mathematical expression to have meaning, it needs to include variables like x, y, and z as well as mathematical operations like addition, subtraction, multiplication, and division. Algebra is used in every area of mathematics, including coordinate geometry, calculus, and trigonometry. A straightforward algebraic expression is 2x + 4 = 8.
Given that :While shopping, Betty spent three times as much as Nan. And they spent a total of $120,
Let the Betty spent total $x and Nan spent total $Y
then,
x = 3y ....(i)
x +y =120 .....(ii)
