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

Explanation:

Step 1: Define

Point (6, 9)

Point (3, -3)

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]:                                                                 $\displaystyle m=\frac{-3-9}{3-6}$
2. [Fraction] Subtract:                                                                                             $\displaystyle m=\frac{-12}{-3}$
3. [Fraction] Divide:                                                                                               $\displaystyle m=4$
