Question

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

If JK = 10 and J lies at -17, where could K be located?
If there is more than one location, separate them with commas.

Answer 1

-7, -27

Explanation:

J is at -17. K is 10 units from J.

Start at point J, -17:

a) If you go 10 units to the right, you end up at -17 + 10 = -7

b) If you go 10 units to the left, you end up at -17 - 10 = -27

J can be at -7 or at -27

Answer: -7, -27
