Question

Suppose that J and K are points on the number line.

If JK = 14 and J lies at -5, where could K be located?
If there are several locations, separate them with commas.

Answer 1

9, -19

Explanation:

Given that the distance between point J and point K on a number line is 14, and the coordinate of J is -5, there are two possible coordinates that could represent the location of K.

K can either be located to the right of J, or to the left of J. Either ways, distance between J and K will still equal 14.

To the right we would have K located at: -5 + 14 = 9

To the left we can also have K located at: -5 - 14 = -19

K can be located at either 9 or -19
