% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-9-(-8)}{-3-(-2)}\implies \cfrac{-9+8}{-3+2}[/tex]
The answer is C, 1.
y₂ - y₁ -9 + 8 -1
---------- = ----------- = ------ = 1
x₂ - x₁ -3 + 2 -1
y₂ - y₁ -9 + 8 -1
---------- = ----------- = ------ = 1
x₂ - x₁ -3 + 2 -1
