By definition, the slope or gradient of a line describes its steepness, incline, or grade.
Where
m — slope
θ — angle of incline
If the 2 Points are Known
Result
Slope (m) =
ΔY
ΔX
=
-2
1
= -2
θ =
arctan( ΔY ) + 360°
ΔX
= 296.56505117708°
ΔX = 6 – 0 = 6
ΔY = -4 – 8 = -12
Distance (d) = √ΔX2 + ΔY2 = √180 = 13.416407864999
Equation of the line:
y = -2x + 8
When x=0, y = 8
When y=0, x = 4
