Frequently Asked Questions
What is point-slope form?
Point-slope form is y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is a point on the line. It's useful when you know a point and the slope.
How do I convert point-slope to slope-intercept?
Expand: y - y₁ = m(x - x₁) becomes y = mx - mx₁ + y₁, so y = mx + b where b = y₁ - mx₁.
