There are three basic forms of the line equation:

1. General Equation: Ax + By + C = 0 where A,B, and C are constants for which A and B are not both equal to zero.

2. Point - Slope Equation: (y - y_{1}_{) }= m(x - x_{1}) where x_{1}, y_{1}, and m are constants; (x_{1},y_{1}) is a point on the line and m is the slope.

3. Slope-Intercept Equation: y = mx + b where m and b are constants and b is the y-intercept.
