Given:

On a number line, suppose point E has a coordinate of - 4, and EG = 4.

To find:

The possible coordinates of point G.

Solution:

It is given that, point E has a coordinate of - 4, and EG = 4. It means, point G is either 4 units left from point E or 4 units right from point E.

If the point G is 4 units left from point E, then

If the point G is 4 units right from point E, then

Therefore, the possible coordinates for G are -8 and 0.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
