• Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Point (-9, 15)

Point (-9, -8)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

1. Substitute in points [SF]:                     $\displaystyle m=\frac{-8-15}{-9+9}$
2. [Fraction] Subtract/Add:                     $\displaystyle m=\frac{-23}{0}$

Here we see that our slope would be undefined since we cannot divide anything by 0.
