Question

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

Answer 1

The answer is A) y= 3 X+1

Explanation:

I broke it down on paper.

Answer 2

A) y= 3 X+1

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
