- Slope Formula: [tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
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
- Substitute in points [SF]: [tex]\displaystyle m=\frac{-8-15}{-9+9}[/tex]
- [Fraction] Subtract/Add: [tex]\displaystyle m=\frac{-23}{0}[/tex]
Here we see that our slope would be undefined since we cannot divide anything by 0.
