  1. No, your equation is not the answer. Check it yourself by seeing what y is when x = 0 (the y-intercept point). Your equation gives y = 8, and it should give y = 4.

    Solve it by first trying the y = mx + b form, where b is the y-intercept and m is the slope.
    y = mx + 4
    When y = 0 (the x-intercept), x = 8, so
    0 = m*8 + 4
    m = -1/2
    y = -x/2 + 4
    or
    x + 2y = 8 is the answer.
    You could also write it as
    4x + 8y = 32
