    First, find the slope using the equation, y2 – y1 / x2 – x1

    1-5 / 4 – – 4 = -4/8 =  -1/2

    plug this into slope intercept form

    y = -1/2x + b

    Next use one of the points to find b using point-slope form. I will use (4,1)

    y – y1 = m ( x – x1)

    y – 1 = -1/2 (x – 4)

    y -1 = -1/2x + 2

    +1                  +1

    y = -1/2x + 3 is your equation
