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?

Answer 1

See there can be two cases:
case 1:If he is selling all 13 cars at the end of every 3rd month.
Then as the 1st graph shows,there are overall two slopes which are 1 and 0.
case2:If he is selling 13 cars in 3 months and all the 13 cars sold every 3 months are sold at constant rate in between these three months.
Then the graph is a straight line with slope 1.
