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

the answer is 13/3 ( I got a 100% on the test)

Explanation:

Answer 2

Slope of the line is 13/3

Explanation:

• Step 1: Given that time is along the x-axis and the number of cars along the y-axis, the coordinate after 3 months is (3,13) and after 6 months is (6,26).
• Step 2: Find the slope of the line, m = (y2 - y1)/(x2 - x1)

⇒ m = (26 - 13)/(6 - 3) = 13/3
