Answer:
4, 0, 3
Explanation:
You want to know which numbers are possible values of m, given a graph of the values of m.
Interpreting a number line graph
The graph shows an empty circle at m=6, and an arrow extending to the left from that point. The empty circle means that m=6 is not a possible value of m.
The arrow extends through possible values of m, and extends to negative infinity. That means m may have any value less than 6. Such values on the offered list are ...
4, 0, 3
__
Additional comment
The values 6, 7, 9 are not covered by the dot or the arrow, so are not possible values of m.
