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 = [tex]\frac{Rise }{horizontal distance}[/tex]
Simply to find slope;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
First point = (12, -5), x₁ = 12 and y₁ = -5
Second point = (10, -4), x₂ = 10 and y₂ = -4
Input the parameters:
Slope = [tex]\frac{-4 -(-5)}{10 - 12}[/tex]
= [tex]\frac{-4 + 5}{-2}[/tex]
= - [tex]\frac{1}{2}[/tex]
The slope of the line is -[tex]\frac{1}{2}[/tex]
