    Answer:

    see graph  (4,4)

    to manually graph just pick any two values for X in the first equation and calculate the corresponding Y value … put a “dot” (a point on the graph)

    do for both points , and draw al LINE between them…

    repeat fore the second equation… the “solution” is where the two lines cross

    Answer:

    (4,4)

    y = 4

    x = 4

    Step-by-step explanation:

    First we need to input y = 1/2x + 2 into 4x – 2y = 8.

    4x – 2 (1/2x + 2) = 8 <– Then solve

    4x – 1x + -4 = 8

    3x – 4 = 8

        +4   +4

    ———————

    3x    =    12

    3             3

    x = 4

    Now we need to use x and apply it to find y.

    y = 1/2x + 2

    y = 1/2(4) + 2

    y = 2 + 2

    y = 4

    Now to graph go on the x axis (horizontal axis) and go to 4, then up 4 on the y axis.

    You need to graph the point (4,4).

    I hope this helps!
