    Answer: The whole solution is (4,6)  so the  y coordinate of the solution is 6.

    Step-by-step explanation:

    y = -1/2x + 8     and y= x +2

    Using both equations substitute one of the equation into another an solve for x.

    -1/2x + 8  = x + 2

             -8          -8

    -1/2x = x  -6

    -x          -x  

    -1.5x = -6

     x =  4

    Since the value of x is 4 input in into the equation and solve for y.

    y = -1/2(4) + 8

    y = -2 + 8

    y = 6
