خط تعريف

The equation of a vertical line is x = k, where a represents the x-intercept. The graph below provides an example of the equation of a vertical line.

الخصائص

The equation of a vertical line does not have a y-intecept since a vertical line never crosses the y-axis. If it runs directly through the y-axis (x = 0) then it technically intersects the y-axis and has many y-intercepts.
The slope of a vertical line is undefined because the denominator of the slope (the change in ΔX) is zero.
