I'm pretty sure it would be d. you have to add the xs and ys and divide each by 2.
The given line has a slope of -1 so the perpendicular line will have a slope of -1/1=1
y=x+5
The cost per unit of the auto shop function is the slope of the function
87 represents the slope and the cost per tire purchased
The function is given as:

A linear function is represented as:

Where:
m represents the slope or the unit rate.
So, by comparison:

This means that 87 represents the slope and the cost per tire purchased
