First answer: infinitely many
Second answer: 2 or anything to the right of 2
Saying "m is greater than or equal to 2" basically means m = 2 is possible, or anything larger than 2 is possible. The numbers go on forever beyond 2, so there are infinitely many possibilities for m (example: m = 23 or m = 678).
Note: the graph on a number line will show a closed filled in circle at 2 with shading to the right. The shading shows all the possible answers.
