What would a number line representing g≠7 look like?

Answer 1

A number line representing g≠7 would have a circle around the number 7 (indicating it is not included in the solution set) and an arrow pointing in both directions from the circle to show that g can be any number except 7. The number line would look like this:

< ----o----------o-----------o------------o----------o---->

where the o represents the circle around 7 and the dashes represent all other numbers on the number line.
