- Slope Formula: [tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
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]: [tex]\displaystyle m=\frac{-21+10}{4-3}[/tex]
- [Fraction] Add/Subtract: [tex]\displaystyle m=\frac{-11}{1}[/tex]
- [Fraction] Divide: [tex]\displaystyle m=-11[/tex]
