- Different Forms. There are many ways of writing linear equations, but they usually have constants (like "2" or "c") and must have simple variables (like "x" or "y").
- Slope-Intercept Form. The most common form is the slope-intercept equation of a straight line: Slope (or Gradient) Y Intercept. Example: y = 2x + 1. Slope: m = 2.
- Point-Slope Form. Another common one is the Point-Slope Form of the equation of a straight line: y − y1 = m(x − x1) Example: y − 3 = (¼)(x − 2) It is in the form y − y1 = m(x − x1) where
- General Form. And there is also the General Form of the equation of a straight line: Ax + By + C = 0. (A and B cannot both be 0) Example: 3x + 2y − 4 = 0. It is in the form Ax + By + C = 0 where
