No real x works — those four points cannot be the vertices of a rectangle.

Reason: in any rectangle (a parallelogram) the y-sums of the two opposite-vertex pairs must be equal. The three given y-values are 5, 1, −4 and the fourth is 2. The three ways to pair them as opposite vertices give y-sums:

- (5 + 1) = 6 vs (−4 + 2) = −2
- (5 + (−4)) = 1 vs (1 + 2) = 3
- (1 + (−4)) = −3 vs (5 + 2) = 7

None of these match, so no x can make the four points form a rectangle.
