  • Write the equation of the line.
    y = -2x - 4
  •  15
  • Write the equation of the line.
    y = (2/5)x + 1
  •  15
  • Write the equation in slope-intercept form: x = -5 + y
    y = x + 5
  •  15
  • Solve the equation for y: 0 = -x + 25 + 5y
    y = (1/5)x - 5
  •  20
  • Solve the equation for y: -4y - 5x = 0
    y = (-5/4)x
  •  20
  • Solve the equation for y: -7x + 5y = -25
    y = (7/5)x -5
