Question

Points Y and Z are the same distance from point X on a number line. The coordinate of point X is 3 and the coordinate of point Y is –2.

What is the coordinate of point Z

______

Answer 1

Coordinate of point Z is 8. That is because the distance from point X to point Y is 3-(-2)=3+2=5, and same is from point X to point Z: 3+5=8. So the answer is Z=8.
