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

Substitute in points [Slope Formula]: $\displaystyle m=\frac{-21+10}{4-3}$
[Fraction] Add/Subtract: $\displaystyle m=\frac{-11}{1}$
[Fraction] Divide: $\displaystyle m=-11$
