What is the x intercept for the following equation ?
4x - 10y = 20

• x - int = 4    
  y-int = -10

• x-int = 5
  y-int = 2

• x - int = 5
  y int = -2

• x -int = 4
  y -int = -10

Write the following equation in slope-intercept form:
4x - 3y = 12

• y = -4/3x + 3

• y = -4x + 12

• y = 4/3x - 4

• y = 4/3x - 12
