Question

Which equation is equivalent to the equation 9x – y = 12?

A. y = -9x+12
B. y= 9x + 12
C. y= -9x - 12
D. y= 9x -12

Answer 1

(D) y = 9x + 12

Explanation:

Answer 2

D. y = 9x - 12

Explanation:

Isolate y:

9x - y = 12

Add y to both sides:

9x = y + 12

Subtract 12 from both sides:

y = 9x - 12
