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

Step-by-step explanation:

Step 1: Define

Point (3, -10)

Point (4, -21)

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]:                                                             $\displaystyle m=\frac{-21+10}{4-3}$
2. [Fraction] Add/Subtract:                                                                                 $\displaystyle m=\frac{-11}{1}$
3. [Fraction] Divide:                                                                                             $\displaystyle m=-11$
