- Slope Formula: [tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Step-by-step explanation:
Step 1: Define
Find points from graph.
Point (0, 40)
Point (20, 50)
Step 2: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m
- Substitute [SF]: [tex]\displaystyle m=\frac{50-40}{20-0}[/tex]
- Subtract: [tex]\displaystyle m=\frac{10}{20}[/tex]
- Simplify: [tex]\displaystyle m=\frac{1}{2}[/tex]
