Point-Slope Form Calculator
How It Works
This point-slope form calculator uses established formulas to provide accurate results.
The basic rule:
- y - y₁ = m(x - x₁)
- y = mx + b where b = y₁ - mx₁
- Standard form: Ax + By = C

What is point-slope form?
Point-slope form is y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is a known point on the line. It is useful when you know one point and the slope.
How do I convert point-slope to slope-intercept form?
Distribute the slope m on the right side, then add y₁ to both sides to isolate y. This gives you y = mx + b form.
What is standard form of a line?
Standard form is Ax + By = C, where A, B, and C are integers and A is positive. You get this by rearranging slope-intercept form.
