Which points in the graph represent a solution to the equation 𝑥 equals three?

The 𝑥-axis is the horizontal one and, in this case, goes from negative four to 10. The line that corresponds to the equation 𝑥 equals three will be a vertical line through three on the 𝑥-axis. We can go one step further here and say that any equation of the form 𝑥 equals 𝑎, where 𝑎 is a constant, will be a vertical line through the constant 𝑎.

In this question, the line with the equation 𝑥 equals three passes through the points 𝐺, 𝐼, and 𝐾.
