Which equation is equivalent to 2x + 6y = 12?
a. y= 1/3x+ 2
b. y= 1/3x-2
c. y= -1/3x+2
d. y= -1/3x -2

2x + 6y = 12
6y = -2x + 12
y = -2x/6 + 12/6
y = -1/3 x + 2

The correct answer among all the other choices is c. y= -1/3x+2. This equation is equivalent to 2x + 6y = 12. Just move all the equation that don't contain y to the right side then solve. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
