Answer:
what is this
Step-by-step explanation:
Given parameters:
First point = (12, -5)
Second point = (10, -4)
Unknown:
Slope of the line = ?
Slope is simply the vertical rise divided by the horizontal distance.
Slope = 
Simply to find slope;
Slope = 
First point = (12, -5), x₁ = 12 and y₁ = -5
Second point = (10, -4), x₂ = 10 and y₂ = -4
Input the parameters:
Slope = 
= 
= - 
The slope of the line is -
Move constant over (5x=38+2), combine terms (5x=40), divide both sides by 5 (x=8)
