Find the x-intercept and y-intercept of the line.

3x + 6y=-18

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

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).
