Question

A store sells small pumpkins. The graph shows the cost c of p pumpkins. Write an equation that represents c.

Answer 1

c = 5p

Explanation:

Since the line passes through the origin the equation is of the form

c = mp ( m is the slope )

Consider the points (0, 0 ) and (1, 5 ), then

m =
`(rise)/(run)` =
`(5)/(1)` = 5

The equation representing the quanties is

c = 5p
