Final answer:
The slope of the linear function is $1.75 per mile and the y-intercept is $50.
The equation C(x) = $50 + $1.75x
Step-by-step explanation:
The linear function, C(x), is given by the equation C(x) = $50 + $1.75x, where x is the number of miles driven.
The slope of the linear function is $1.75 per mile.
The units for the slope are dollars per mile.
The y-intercept of the linear function is $50.
The units for the y-intercept are dollars.
