- The slope of the line that passes through the points (2, 1) and (2, 0) is [tex]\infty[/tex]
- The slope of a vertical line does not exist, hence the equation of the line cannot be written in point-slope form
The formula for finding the slope of a line is expressed as:
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Given the coordinate points (2, 1) and (2, 0). Get the slope of the line passing through the coordinate points
[tex]m=\frac{0-1}{2-2}\\m=\frac{-1}{0}\\m=\infty[/tex]
The equation of the line in point-slope form is [tex]y-y_0=m(x-x_0)[/tex]
Since the slope of a vertical line does not exist, hence the equation of the line cannot be written in point-slope form
