Frequently Asked Questions
How do I find the line equation from two points?
Calculate slope: m = (y₂ - y₁)/(x₂ - x₁). Then find y-intercept: b = y₁ - mx₁. The equation is y = mx + b.
What if the line is vertical?
If x₂ = x₁, the line is vertical (undefined slope) and the equation is x = x₁ (or x = x₂).
