    Answer:

    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
