Slope formula
m = y₂- y₁/ x₂- x₁
Ordered pair
(4, 5)(- 8, 6)
m = 6 - 5 / - 8 -4
m = 1 / - 12
m = - 1/ 12
- - - - - - - - - - - -
Slope intercept form
y = mx + b
5 = - 1/12(4) + b
5 = - 4/12 + b
5 = - 1/3 + b
5 + 1/3 = - 1/3 + b + 1/3
15/3 + 1/3 = b
16/3 = b
- - - - - - -
The equation
y = - 1/12 + 16/3
- - - - - - - -s-

Slope is change in y/change in x
y1-y2/x1-x2
(5-6)/(4--8)=
-1/12 is your slope

(4, 5) (-8, 6)
(6 - 5) / (8 - 4) = 1/4
