B) Find the equation of the trend line (line of best fit). Show your work. (2 points)

Sadly, no trend line was placed for this question. Try again.

Using the point-slope form:

The equation of the line is given by:

[1]  where

m is the slope of the line and  is the point on the line.

As per the statement:

Given: Two points i,e (34, 76) and (42, 91)

First calculate slope(m):

Slope is given by:

Substitute the given values we have;

Now, substitute the value of m and (34, 76) in [1] we have;

Using distributive property:  

Add 76 to both sides we get;

Therefore, the equation of the trend line is:

Step-by-step explanation:

Assuming both rented from the same store and the rental price is the same.

$230 -  $125 = $105
5hours - 2hours = 3hours
3hours = $105
1 hour = $105 ÷ 3 = $35
So the price of 1 of one hour rental is $35.

2hours = $35 x 2 = $70
Lori paid $125
Therefore the flat setup fee = $125 - $70 = $55

Ans:  Setup fee = $55, rental fee = $35/hour
