Work Step by Step

RECALL: A line with an undefined slope has an equation of the form $x=h$ where $h$ is the x-intercept. All points on the line have $x=h$. The given line has an undefined slope, so it is a vertical line. The line contains the point $(2, 4)$. This means that all points on the line have $x=2$, and that the equation of the line itself is $x=2$. Thus, the equation of the line is: $\color{blue}{x=2}$
