Question

Select the equations of the lines that are parallel to the line whose equation is y = 3x + 5:

6x + 2y = 12
-3x + y = 8
3y = 9x
y = -x

Answer 1

-3x+y=8 and 3y=9x

Explanation:

Answer 2

-3x+y=8 and 3y=8

Explanation:

-3x+y=8

+3x +3x

y=3x+8

3y=9x

Divide 3 on both sides to get y by itself.

The answer is y=3x
