• Coordinates (x, y)
• Slope Formula: $\displaystyle m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step 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]:                                                             $\displaystyle m=\frac{-1-2}{4-0}$
2. [Fraction] Subtract:                                                                                         $\displaystyle m=\frac{-3}{4}$
