Exercise 1 Page 84

How can you use the points on the direct variation graph to find the constant of variation?

15 cakes per hour

Practice makes perfect

We want to find the constant of variation of the given direct variation graph. Let's take a look.

Next, we will use the points marked on the graph to find the constant of variation.

x	y	Constant of variation, yx
2	30	30/2= 15
4	60	60/4= 15

This constant tells us that the ratio of cakes baked to hour worked is 15 cakes per hour.
