Point Slope Form

Point-slope form is a form of graphing the linear equation on the coordinate plane. It is one of the three common ways to represent lines as equations; the other two are standard form ($Ax+By=C$) and slope intercept form ($y=mx+b$).


Given a point on a line in the coordinate plane, $(a,b)$ and the slope of the line, $m$, the equation $y-b=m(x-a)$ is satisfied for all points on the line.
