    Answer: Answers below

    Step-by-step explanation:

    2y+4x=8

    Solve for y.

    2y+4x-4x=8-4x\\2y=8-4x\\y=\frac{8-4x}{2}

    ———————————————-

    When x = -2; y = 8

    y=\frac{8-4(-2)}{2}\\y=\frac{8+8}{2}\\ y=\frac{16}{2}\\ y=8

    ———————————————-

    When x = 1 ; y = 2

    y=\frac{8-4(1)}{2}\\y=\frac{8-4}{2}\\ y=\frac{4}{2}\\ y=2

    ———————————————-

    When x = 3 ; y = -2

    y=\frac{8-4(3)}{2}\\y=\frac{8-12}{2}\\ y=\frac{-4}{2}\\ y=-2
