• x = 14

• x = -10

• x = 8

• x = 0

Write the equation ⅛ y = -¾x - 1 in standard form.

• 3x + y = -8

• 6x + y = 8

• -3x + y = 8

• 6x + y = -8

Write the equation 5y = 35 + 10x in standard form.

• 2y - 4x = 7

• 2x-y= -7

• 4x + 2y = 7

• 5y = 35 - 10x

Write the equation x - 4y = 28 in slope-intercept form, then graph the line on your paper.

• y = (1/4)x - 7

• y = 4x + 28

• y = -4x + 28

• y = (1/4)x + 7
