• Coordinates (x, y)
• Slope Formula:
  `\displaystyle m = (y_2-y_1)/(x_2-x_1)`

Explanation:

Step 1: Define

Identify

Point (-3, 0)

Point (-3, 11)

Step 2: Find slope m

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

1. Substitute in points [Slope Formula]:
   `\displaystyle m = (11-0)/(-3--3)`
2. [Fraction] Subtract:
   `\displaystyle m = (11)/(0)`
3. [Fraction] Simplify: m = undefined

∴ We have a vertical line at x = -3.
