x > 4
The dot is placed on the number 4 on the number line. x represents a variable. If you analyze the graph, it says that x could be any number after 4 because a line is extending from 4 to the right of the number line.
Sometimes, the dot on a graph is sometimes filled in or transparent:
- A filled in dot means ur choices are either ≥ or ≤.
- A transparent dot (like in this graph) means ur choices are either < or >.
Have a nice day
