    Answer:

    The slope would be 2/-4. Rise 2 and go left 4.

    Hope this helps

    Answer:

    y = -1/2x+7

    Step-by-step explanation:

    First find the slope using the slope formula

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

       = (3-5)/( 8-4)

       = -2/4

      = -1/2

    The slope intercept form is

    y = mx+b where m is the slope and b is the y intercept

    y = -1/2x+b

    Substitute a point into the equation

    3 = -1/2(8) +b

    3 = -4+b

    Add 4 to each side

    3+4 = -4+b+4

    7 = b

    y = -1/2x+7
