Question

The graph of y=3x is shown. What is the value of x when y=27?

A. 2

B. 3

C. 9

D. 24

Answer 1

The answer is c
it is since you would put 3x = 27
then divide 3 by 27 which equals 9!

Answer 2

C

Explanation:

Our equation is y=3x.

We can plug in 27 for y, to find x when y is 27.

27=3x

Divide both sides by 3 to reverse the multiplication.

x=9

C
