Pre-Algebra
- Order of Operations: BPEMDAS
- Equality Properties
Algebra I
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
Step 1: Define
Find points from the graph.
x-intercept (2, 0)
y-intercept (0, -1)
Step 2: Find slope m
- Substitute: [tex]m=\frac{-1-0}{0-2}[/tex]
- Subtract: [tex]m=\frac{-1}{-2}[/tex]
- Simplify: [tex]m=\frac{1}{2}[/tex]
Step 3: Write linear equation
y = 1/2x - 1
