What does point-slope equation of a line refer to in analytic geometry?

A point-slope equation of a line refers to Cartesian coordinates: If a point has coordinates (x1, y1) on a line and a slope equal to m, then the equation y - y1 = m(x - x1) is the point-slope equation. Point-slope is most often used when finding an equation of a line.
