Will give
the cost c, in dollars, of renting a moving truck for a day is given by the function upper c left parenthesis x right parenthesis equals 0.25 x plus 40 comma where x is the number of miles driven.
(a) what is the cost if a person drives x equals 240 miles?
(b) if the cost of renting the moving truck is $180, how many miles did the person drive?
(c) suppose that a person wants the cost to be no more than $150. what is the maximum number of miles the person can drive?

the answers c

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
