Exercise 48 Page 173

What is the form of a direct variation equation?

$y = 33$

Practice makes perfect

Functions where

y

varies directly with

x,

direct variation equations, follow a specific format.

y = m x

In this form,

m \neq = 0 .

By substituting the given values for

x

and

y

into the equation, we can determine the constant of variation,

m .
