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

Step-by-step explanation:

Step 1: Define

Point (-6, 3)

Point (-6, 39)

Step 2: Find slope m

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

1. Substitute [SF]:                     $\displaystyle m=\frac{39-3}{-6+6}$
2. Subtract/Add:                       $\displaystyle m=\frac{36}{0}$

Anything that is being divided by 0 would be undefined (we do not know what any number is divided by 0).
