Key Concepts

Property To find the exact input value (x) where two linear functions produce the exact same output (y), set their equations equal to each other and solve for x:.

$$m 1x + b 1 = m 2x + b 2$$.

Examples Example 1: Find where y = 3x + 4 and y = 5x 2 are equal. Set them equal: 3x + 4 = 5x 2. Subtract 3x from both sides: 4 = 2x 2. Add 2: 6 = 2x, which simplifies to x = 3.
