Answer:

The y-intercept is (0, -3).  The x-intercept is (-6, 0).

Step-by-step explanation:

y-intercept:  Let x = 0 and solve the resulting equation for y:

   3(0) + 6y = 18, or 6y = -18, or y = 3.  The y-intercept is (0, -3).

x-intercept:  Let y = 0 and solve the resulting equation for x:

    3x + 6(0) = -18 yields x = -6.  The x-intercept is (-6, 0).

Answer: y-intercept=-3  (0,-3)        x-intercept=-6  (-6,0)

Step-by-step explanation:

1. to find x substitute y for 0

  • 3x+6(0)=-18
  • 3x=-18

2. divide both sides by 3

  • 3x=-18
  • ÷3    ÷3
  •   x=-6

3. to find y substitute x for 0

  • 3(0)+6y=-18
  • 6y=-18

4. divide both sides by 6

  • 6y=-18
  • y=-3
