    Slope (m) =

    ΔY

    ΔX

    =

    38

    79

    =

    0.48101265822785

    θ =

    arctan (

    ΔY

    ) + 180°

    ΔX

    =

    205.68814343565°

    ΔX = 7 - 86 = - 79

    ΔY = - 56 - - 18 = - 38

    Distance (d) = √ΔX2 + ΔY2 = √7685 = 87.664131775772

    Equation of the line:

    y = 0.48101265822785x - 59.367088607595

    or

    y =

    38

    x

    79

    -

    4690

    79

    When x=0, y = - 59.367088607595

    When y=0, x = 123.42105263158
