The linear equation relating the given condition is y + 10x - 62 = 0 .
Each solution in the scenario with two variables can be understood as the Cartesian coordinate system of such a point on the Euclidean plane.
A line in the Euclidean space is formed by a linear equation's solutions, and every line may be thought of as the collection of all solutions to a linear equation with two variables. This is where the term "linear" for this class of equations came from. In the Euclidean space of dimension n, the equations of a linear equation with n variables generate a hyperplane (a subset of dimension n 1).Let the linear relation between the two variables be given by y=mx + c
Now we put the values to get the constants.
58 = 2m + c
52 = 5m + c
solving we get :
52 - 5m = 58 - 2m
or, -6 = 3m
or, m = -2
Now we put those values in the equations
52 = 5m + c
or, 52 = -10 + c
or, c = 62
The equation relating the sunglasses is y + 10x - 62 = 0 .

Step-by-step explanation:
What is the slope of the line through (-9,6) and (-3,9)? Choose 1 answer: A 2 B 1 2 1 2 D -2
The slope according to the given points of line is (B) m = 1/2.
What do we mean by slope?Slope, the inclination of a line with respect to the horizontal is measured numerically. The ratio of the vertical to the horizontal distance between any two points on a line, ray, or line segment is known as its slope in analytic geometry ("slope equals rise over run"). The slope-intercept form of an equation is used whenever the equation of a line is expressed in the form y = mx + b. M represents the line's slope.So, points are: (-9,6) and (-3,9)
Slope formula: m = (y₂ - y₁)/(x₂ - x₁)Now, substitute the values in the formula as follows:
m = (y₂ - y₁)/(x₂ - x₁)m = (9 - 6)/((-3) - (-9))m = (9 - 6)/((-3) + 9))m = 3/6m = 1/2Therefore, the slope according to the given points of the line is (B) m = 1/2.

The x and y intercepts of the given graph of the function are 3/2 and -1 respectively.
Intercepts of the line
The point where the line or curve crosses the axis of the graph is called intercept. If a point crosses the x-axis, then it is called the x-intercept. If a point crosses the y-axis, then it is called the y-intercept.
Given equation of the line:
y = (2/3)x - 1
To find the y -intercept, putting x = 0, we get,
y = (2/3)*0 - 1
y = 0 - 1
y = -1
Hence, the y - intercept is -1.
To find the x -intercept, putting y = 0, we get,
0 = (2/3)x - 1
1 = (2/3)x
x = 3/2
Hence, the x - intercept is 3/2.

Write the equation of the line that is perpendicular to the given line and goes through
the point (8, 2).
The equation of the line which is perpendicular and goes through the point (8,2) is slope-intercept form of y = x - 6.
What is slope-intercept form?
A line's equation can be written in the slope-intercept form such that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are instantly visible. This form is commonly referred to as the y = mx + b form.The equation of the line which is perpendicular and goes through the point (8,2) is y = x - 6
The equation of the required line in slope-intercept form is expressed as:
y-y0 = m(x-x0) where:
m is the slope
(x0, y0) is the point on the lin
Given the equation of the line as y = -x
Get the slope of the line
mx = -x
m = -1
Since the required line is perpendicular to this line, the required slope will be 1 (M = -(-1/1))
y-y0 = m(x-x0)
y - 2 = 1(x-8)
y - 2 = x - 8
y = x - 8 + 2
y = x - 6
Hence the equation of the line which is perpendicular and goes through the point (8,2) is y = x - 6.

The principal P is borrowed and the loan's future value A at time t is given. Determine the loan's simple interest rate r
P= $5000.00, A = $6250.00, t= 5 years
Simple interest typically favors consumers who pay their bills or loans on time or early each month because it is frequently calculated on a daily basis. The loan's simple interest rate is 4.5%.
Who benefits from a simple interest loan?Simple interest typically favors consumers who pay their bills or loans on time or early each month because it is frequently calculated on a daily basis.
In the aforementioned student loan example, if you paid a $300 payment on May 1st, $238.36 would be applied to the principle. On April 20, if you made the same payment, $258.91 would be applied to the principal. Your main balance will decrease more quickly and the loan will be paid off faster than anticipated if you can make an early payment every month.
On the other hand, if you pay the loan back late, you pay more in interest than if you pay it on time. If your payment is due on May 1 and you make it on May 16 (using the same car loan example), you will be charged interest for 45 days at a cost of $92.46. Consequently, only $207.54 of your $300 payment is applied to the principal. If you frequently make late payments over the course of a loan, your final payment will be more than anticipated because the principal did not decrease at the anticipated rate.
Principal amount,
P=$5000
Future value,
A=$5900
Time,
t=4years
Let us determine the loan's simple interest rate:
A=P(1+rt)
5900=5000(1+r*4)
5900=5000(1+4r)
5900=5000*1+5000*4r
5900=5000+20000r
5900−5000=20000r
900=20000r
20000r=900
r=900/20000
r=9/200
r=0.045
r=0.045/100%
r=4.5%

It is often displayed horizontally and can extend indefinitely in any direction. A number line is exactly what it sounds like—a horizontal, straight line with numbers spaced evenly apart throughout its length.

Express the confidence interval (78.5,154.7) in the form of ¯x± ME (Error Bound).
The expression of the confidence interval (78.5, 154.7) in the form of x¯ ± ME is; CI = 116.6 ± 38.1
How to find the Confidence Interval?
We are given the confidence interval as;
CI = (78.5, 154.7)
Now, we want to express the given confidence interval in the error bound form which is; x¯ ± ME
where;
x¯ is sample mean
ME is margin of error
Now, the boundaries of the interval as two points is the midpoint between them which would be (78.5 + 154.7)/2 = 116.6.
This is right in the middle of 78.5 and 154.7.
This value of 116.6 is the sample mean represented by x¯, since x¯ is in the middle of the interval. This means that 78.5 and 154.7 are the same distance (the margin of error, ME) away from 116.6. .
116.6 - 78.5 = 38.1 and 154.7 - 116.6 = 38.1
