• Slope Formula:
  `m=(y_2-y_1)/(x_2-x_1)`

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=(0-1)/(0-2)`
2. Subtract:
   `m=(-1)/(-2)`
3. Simplify:
   `m=(1)/(2)`
