Answer:
-21, 13
Explanation:
If Z is located to the right of Y, its point on the number line is -4+17 = 13.
If Z is located to the left of Y, its point on the number line is -4-17 = -21.
There are two possible locations for Z on a number line.
_____
In a 2-dimensional plane, there are an infinite number of locations of distance 17 from a given point. The set of all of them makes a circle on the plane, with radius 17.
In 3-dimensions, the set of points becomes a sphere with radius 17.
