Find the x and y intercepts -3x-6y=12

Step-by-step explanation:

The x-intercept is found where the graph crosses the x-axis, at y=0. Substituting that into the equation and solving for x, we get ...

  -3x = 12

  x = 12/-3 = -4 . . . . . x-intercept = -4

The y-intercept is found where the graph crosses the y-axis, at x=0. Substituting that into the equation and solving for y, we get ...

  -6y = 12

  y = 12/-6 = -2 . . . . . y-intercept = -2
