Question

The x-coordinate of the point lying on the perpendicular bisector of the line segment joining the points A(–2, –5) and B(2, 5) is ______.

Answer 1

The x-coordinate of the point lying on the perpendicular bisector of the line segment joining the points A(–2, –5) and B(2, 5) is zero.

Explanation:

The perpendicular bisector passes through the midpoint of AB.

Midpoint of A(–2, –5) and B(2, 5) is `((-2 + 2)/2, (-5 + 5)/2) = (0, 0)`.

So the x-coordinate is 0.
