Question

point es x-coordinate is 0, but its y-coordinate is not 0.
where could point e be located on the coordinate plane?

Explanation:

On a coordinate plane, points with an x-coordinate of 0 lie on the y-axis. Since the y-coordinate is not 0, the point cannot be the origin (0,0), so it must be on the y-axis itself, outside of the four quadrants (which require non-zero x and y coordinates).

Answer:

Point E is located on the y-axis (either the positive y-axis segment above the origin or the negative y-axis segment below the origin, not in any quadrant).
