Question

Points Y and Z are the same distance from point X on a number line. The coordinate of point X is –7 and the coordinate of point Y is –1.

What is the coordinate of point Z?

Answer 1

C)StartRoot 61 EndRoot

Explanation:

Answer 2

Since you know that point Y and point Z are equal distance form point F, you will need to know the distance between point Y, -1, and the distance between point X, -7. So, the total distance, after subtracting -1 from -7, is -6. So, you will then subtract another -6 from -7, to get -13, which is the coordinate of point Z.
