Suppose that Y and Z are points on the number line.
If YZ = 9 and Y lies at -12 , where could Z be located?

If there is more than one location, separate them with commas.

We have been given that Y and Z are points on the number line.   The length of segment YZ is 9 units and Y lies at -12. We are asked to find the location of point Z.

Since Y and Z are located on number line, so Z can be either on left side of Y or on right side of Y.

When Z is on left side of Y, then we can set an equation as:

Therefore, the location of Z will be .

When Z is on right side of Y, then we can set an equation as:

Therefore, the location of Z will be .
