9. Direct Variation

Continue to next subchapter

Exercise 1 Page 84

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, $\frac{y}{x}$
$2$	$30$	$\frac{3 0}{2} = 15$
$4$	$60$	$\frac{6 0}{4} = 15$

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