Point Slope Form However if you are comfortable using the point slope form of a line then skip to the second part of this page because writing the equation from 2 points is easier with point slope form. Instead the equation of a vertical line is in the form. Therefore it cannot be written in slope-intercept form.
For undefined slopes making a slope-intercept ymxb equation isnt useful because we dont have a value for m.
I know it sounds weird. Finding the Equation of a Line Given a Point and a Slope 1 - Cool Math has free online cool math lessons cool math games and fun math activities. As a vertical line will always make an angle. X a where a is the x-intercept.
