Find the slope of the line that passes through (81, - 18) and (7, - 56).

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

When x=0, y = - 59.367088607595

When y=0, x = 123.42105263158
