1) Circle the equation that is NOT an example of direct variation.

A) y = 3 X+1

B) y = 16x

C) y = 4x

D) y=-9x

A) y = 3 X+1

Step-by-step explanation:

A direct variation is of the form

y = kx

A) y = 3 X+1 not a direct variation since we add 1 to it

B) y = 16x direct variation

C) y = 4x direct variation

D) y=-9x direct variation

The answer is A) y = 3 X+1
