    b

    Step-by-step explanation:

    Solution:

    y = - (1/2) x+4

    Standard form of the equation Ax+By=C, with A, B, and C integer numbers

    The coefficient of x is a fraction. To simplify the fraction, let's multiply both sides of the equation by 2:

    2y=2 [ - (1/2) x+4]

    2y=-2 (1/2) x+2 (4)

    2y = - (2/1) (1/2) x+8

    2y=-[ (2*1) / (1*2) ]x+8

    2y = - (2/2) x+8

    2y=-1x+8

    2y=-x+8

    The two variables must be on the left of the equation, then adding x both sides of the equation:

    2y+x=-x+8+x

    x+2y=8
