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

Explanation:

Step 1: Define

Point A(0, 2)

Point B(4, -1)

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=(-1-2)/(4-0)`
2. [Fraction] Subtract:
   `\displaystyle m=(-3)/(4)`
