Answer:
The possible coordinates of point G are; -2 or 4.
Explanation:
A number line can be used to locate the position of any directed number. It has both negative axis and positive axis.
Given that EG = 3, and E has a coordinate of 1, then moving from 1 in the direction of the negative end of the line would make G to be at -2. Also, moving from 1 towards the positive end of the line would make G to be at 4.
Therefore the possible coordinates of point G are -2 or 4, when EG = 3.
