Question

(20,-6)(6,5) find the slope

Answer 1

Slope (m) =
ΔY
ΔX
=
5
4
= 1.25
θ =
arctan( ΔY )
ΔX
= 51.34019174591°
ΔX = 6 – -6 = 12
ΔY = 20 – 5 = 15
Distance (d) = √ΔX2 + ΔY2 = √369
= 19.209372712299

Equation of the line:

y = 1.25x + 12.5

or
y =
5 x
4
+ 25
2
When x=0, y = 12.5
When y=0, x = -10
