When the line neither rises nor falls then we claim that it has a slope of zeroThis is in fact the case of a horizontal line where it extends infinitely to its left or right but without any sign of rising or falling. Represent equations from point slope form to standard form. Seven Point-Slope Form Examples.
Using the Point-Slope Form of a Line Another way to express the equation of a straight line.
To write an equation in point-slope form given a graph of that equation first determine the slope by picking two points. Some people refer to the slope as rise over run. M and want to find other points on the line. The rise is the up distance and the run is the across distance shown in the above figure.
