Graphing Equations
An equation graph represents the set of all ordered pairs (x, y) that satisfy the algebraic equation.
Formula & Step-by-Step Calculation
Linear: y = mx + b, Quadratic: y = ax² + bx + c
Canonical algebraic forms.
Worked Step-by-Step Examples
Example 1
Graph line y = 2x + 1
Solution: Slope m = 2, y-intercept at (0, 1)
• For x = 0, y = 1; for x = 2, y = 5
Common Real-World & Academic Use Cases
