Finding the Equation of a Vertical Line Through and
To find the equation of a line containing the points and , first attempt to calculate its slope using the slope formula. Step — Find the slope. Simplify the denominator by turning the subtraction of a negative into addition (): Because division by zero is mathematically undefined, the slope is undefined. An undefined slope always indicates that the line is vertical. Step — Write the equation. Because both given points have an -coordinate of , every point on this vertical line shares that exact -coordinate. Therefore, the equation of the line is: Because there is no variable, this equation cannot be written in slope-intercept form. Encountering an undefined slope during the two-points procedure is a direct cue to write a vertical line equation .
