Explanation:
Step 1: Define
Point (17, -12)
Point (17, 8)
Step 2: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m
- Substitute in points [Slope Formula]:

- [Fraction - Denominator] Subtract:

We cannot divide anything by 0.
∴ Our slope m is undefined and it would be a vertical line if graphed.
