Answer:
The function is
.
The slope is
.
The y-intercept is
.
Step-by-step explanation:
Our aim is to calculate the values <em>m</em> (slope) and <em>b</em> (y-intercept) in the equation of a line :

We have the following data:

To find the line of best fit for the points given, you must:
Step 1: Find
and
as it was done in the table below.
Step 2: Find the sum of every column:

Step 3: Use the following equations to find <em>b</em> and <em>m</em>:

Step 4: Assemble the equation of a line

The graph of the regression line is:
The answer is 86. Hope this helps.
39 + 0.16m = 25 + 0.24m
39 - 25 = 0.24m - 0.16m
14 = 0.08m
14 / 0.08 = m
175 = m <=== they will cost the same at 175 miles
39 + 0.16(175) = 39 + 28 = $ 67
25 + 0.24(175) = 25 + 42 = $ 67
they will both cost $ 67 <=====
The equation used above is y-intercept form.
ex. y = mx + b
Whatever is in front of the x is your slope.
Your slope is -3
