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

The 𝑥-axis in the graph is the horizontal one. And this goes from negative four to 10. We have circled the point where 𝑥 equals negative three. 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 graph of the equation 𝑥 equals negative three is a vertical line that passes through negative three on the 𝑥-axis. This straight line passes through the four points 𝐴, 𝐶, 𝐸, and 𝐹.
