    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
