Question

Ervin sells vintage cars. Every three months, he manages to sell 13 cars. Assuming he sells cars at a constant rate, what is the slope of the line that represents this relationship if time in months is along the x-axis and the number of cars sold is along the y-axis?
A. 3/13

B. 3

C. 13/3

D. 13

Answer 1

Answer: C. 13/3

Step-by-step explanation:

• Time (in months) = x
• Number of sold cars = y

$slope=\frac{rise}{run} =\frac{y}{x} =\frac{13}{3}$
