On a number​ line, suppose point E has a coordinate of ​-1, and EG=4. What are the possible coordinates of point​ G?

Answer 1

It E is on the number line at -1 and G is 4 units away, you can move to the right by 4 or to the left by 4 to get to G. This can be represented by the following equations:

G = -1+4 = 3

G = -1 - 4 = -5

The two possible locations for G are 3 or -5.
