    (-1,-10) (3,2)

    slope = (2 - (-10) / (3 - (-1) = (2 + 10) / (3 + 1) = 12/4 = 3

    y = mx + b

    slope (m) = 3

    (3,2) ... x = 3 and y = 2

    now we sub and find b, the y int

    2 = 3 (3) + b

    2 = 9 + b

    2 - 9 = b

    -7 = b

    so ur equation is : y = 3x - 7 or f (x) = 3x - 7
