    Answer:

    y = 1/2x+4

    Step-by-step explanation:

    First find the slope

    m= (y2-y1)/(x2-x1)

       = (3 – 5)/(-2 -2)

        = -2/-4

       = 1/2

    Using point slope form

    y -y1 = m(x-x1)  where m is the slope and (x1,y1) is a point on the line

    y-5 = 1/2(x-2)

    Distribute

    y-5 = 1/2x -1

    Add 5 to each side

    y-5+5 = 1/2x -1+5

    y = 1/2x+4
