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

Step-by-step explanation:

Step 1: Define

Random Point (2, 1)

Origin (0, 0)

Step 2: Find slope m

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

1. Substitute [SF]:                    $m=\frac{0-1}{0-2}$
2. Subtract:                              $m=\frac{-1}{-2}$
3. Simplify:                               $m=\frac{1}{2}$
