Slope (m) =
ΔY
ΔX
=
5
3
= 1.6666666666667
θ =
arctan( ΔY )
ΔX
= 59.036243467926°
ΔX = 2 – -10 = 12
ΔY = 13 – -7 = 20
Distance (d) = √ΔX2 + ΔY2 = √544
= 23.323807579381

Equation of the line:

y = 1.6666666666667x + 9.6666666666667

or
y =
5 x
3
+ 29
3
When x=0, y = 9.6666666666667
When y=0, x = -5.8
