Question

1. a line represents the relationship between the number of miles traveled (x) and the total cost (y) of a car rental. if the equation of the line is y = 0.50x + 20, what does the slope represent?

a. the cost of 20 miles driven.
b. the number of miles driven.
c. the total cost of the rental.
d. the cost per mile driven.

Explanation:

The given equation is in the slope-intercept form \(y = mx + b\), where \(m\) is the slope. Here, \(x\) is miles traveled and \(y\) is total cost. The slope \(0.50\) is the rate of change of total cost with respect to miles, meaning it is the additional cost for each mile driven.

Answer:

d. The cost per mile driven.
