Question

Tell whether x and y show direct variation. Explain your reasoning.

Here are the answer choices

A. yes, it can be written as y = mx, where the slope is 1/4

B. yes, it can be written as y = mx, where the slope is 4

C. no, it cannot be written as y = mx

Answer 1

Answer: I may not be correct

This is direct variation. If you move the x to the other side of the equation, it will become:

y = x

Direct variation is when y is equal to x times a constant. In this example, y is equal to 1 * x.
