Solve for y:

2y =-2x + 6

• y = - x + 3

• y = x + 3

• y = 2x +6

• y = - 2x + 6

Solve for y:

3y = -4x +9

• y = -3/4x + 3

• y = -4x + 9

• y = -4/3x + 3

• 3y = -4x + 9

Solve for y:

3y = 18x +9

• y=6x-3

• y=2x-3

• y=-6x+3

• y=6x+3

Solve for y:

2y = -7x+ 20

• y= 7/2x + 10

• y=-7/2x + 10

• y=2/7 x- 10

• y= -2/7x + 10
