Exercise 1 Page 304

A direct variation function follows the form y= mx, where x represents input values, y represents output values, and m represents the constant of variation. Let's consider the given function. 6y=18xSince the given function is not in the form of y= mx, let's try to rewrite it in this form by isolating y.

We were able to write the equation in the form y= mx, so we know that it is a direct variation. We can also identify the constant of variation. y= 3x The constant of variation is 3.
