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
