Answer: m = 1
Step-by-step explanation
First, you must fill in the slope formula:
(7,6) first ordered pair
(6,5) second ordered pair
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
m = [tex]\frac{6-5}{7-6}[/tex] = [tex]\frac{1}{1}[/tex]
The slope is 1.
What is the slope of the line that passes through the points (4,7) and
(7, 16)? Write your answer in simplest form.
The slope of the line passing through (4,7) and (7, 16) is 3
What is Slope ?
The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run". It is denoted by "m".
Formula, m = rise / run = (y2 - y1) / (x2 - x1)
Given,
(x1, y1) = (4, 7)
(x2, y2) = (7, 16)
Now, put these values in slope (m) formula,
m = (y2 - y1) / (x2 - x1)
= (16 -7) / (7 - 4)
= 9/3
= 3
Therefore, the slope of the line passing through (4,7) and (7, 16) is 3.

The midpoint of line segment AB is M(3,-1). If the coordinates of A(8,4), what are the coordinates of B?
The coordinates of B are (-2 , 9)
Step-by-step explanation:
A (8, 4)
M (3 , -1)
To calculate a midpoint you have to add the corresponding coordinates of each point and divide them by 2
(Ax + Bx) / 2 = Mx
(8 + Bx) / 2 = 3
8 + Bx = 3 * 2
Bx = 6 - 8
Bx = -2
(Ay + By) / 2 = My
( -1 + By) / 2 = 4
-1 + By = 4 * 2
By = 8 + 1
By = 9
The coordinates of B are (-2 , 9)

PLEASE HELP !!What is the slope of a line parallel to the line whose equation is 8x+10y=60.
Answer:
In slope intercept form -5y = -4 - 30
Step-by-step explanation:
Slope intercept form is y=mx + b
Rewrite your equation in this form
-10y = -8x - 60
Find GCF (Greatest Common Factor) in this case it is 2
Divide all by 2
-5y = -4x - 30
divide both sides by -5
y = 4/5x + 6
slope = 4/5
Answer:
8
Step-by-step explanation:
so we know the formula of a line is y=mx+b
1. arrange 8x+10y=60 into y=mx+b format
2. 10y=8x+6
3. we see that 8 = m
4. parallel line NEVER intersect so therefore they have the same slope (whereas perpendicular lines intersect so the slope for a perpendicular line would be -1/8)

The first term of the series such that the sum of the first three terms of the geometric series is 171 is equal to 81.
What is the first term of a geometric series?
In this problem we find the sum of three consecutive elements of a geometric series. A geometric series is a set of elements generated by a discrete exponential expression of the form:
y = a · rⁿ ⁻ ¹
Where:
a - First term of the series.r - Common ration - Index fo the element.According to the statement, we find the following expression:
a · (2 / 3)² + a · (2 / 3)¹ + a · (2 / 3)⁰ = 171
(4 / 9) · a + (2 / 3) · a + a = 171
(19 / 9) · a = 171
a = 81

The graph shows the relationship between the number of cups of flour and the number of cookies made. Write an equation for the proportional relationship.
The equation for the proportional relationship is 16x-y=0 .
The equation of the line passing through the two points (a,b) and (c,d) is given by
(y-b) = m(x-a), where m is the slope .
In the question ,
Given in the graph that
x represents the number of cups of flour and y represents the number of cookies made .
From the graph we can see that
when 6 cups of flower is used , 96 cookies are made
So, the point on the line is (6,96),
when 12 cups of flower is used , 192 cookies are made
So, the point on the line is (12,192)
hence the line passes through the two points (6,96) and (12,192).
So the slope of the line is
m=(192-96)/(12-6)
m= 96/6
m=16
Substituting the values of a,b, c,d and m in the equation of line formula ,we get
y-96=16(x-6)
y-96 = 16x - 96
16x-y=96-96
16x-y=0
Therefore , The equation for the proportional relationship is 16x-y=0.

Generally speaking, a function is typically used for mapping an input variable to an output variable. In Mathematics, the value of y on the y-axis of a graph must be less than 0 (x < 0) for the graph of any function to be negative.
By critically observing the graph of this function, we can logically deduce that at point x = 2 is where the value of y becomes less than 0 (x < 0) and continues to infinity. Therefore, the graph of this function is negative is at an interval of 2 < x < ∞.

A rectangular garden is 5 ft longer than it is wide. Its area is 300 ft. What are its dimensions?
The dimensions of the garden are l=20 ft and w=15 ft.
Given, the rectangular garden is 5 ft longer than it's width.
The area of the garden is 300 ft.
dimensions of the garden are = ?
let the width be represented by x.
therefore, length = 5+x
area of the rectangle = l×w
substitute the values.
x(5+x) = 300
5x + x² = 300
x² + 5x - 300 = 0
x²+20x-15x-300 = 0
x(x+20)-15(x+20)=0
(x+20)-(x-15)=0
x=-20 or x=15
hence the dimension cannot be negative.
hence x=15.
substitute x=15 in l=x+5
l=15+5
l=20
Therefore, length and width of the rectangle garden are 20 ft and 15 ft, respectively.
