Answer:
temperature ≤ 6
Step-by-step explanation:
The highest temperature in February was 6°F. Write and graph an inequality to represent this situtation.
If the maximum temperature was 6, then the temperature reached no more than six, while still reaching 6. Thus, the inequality should be
temperature ≤ 6
The graph would be a filled dot on the 6 pointing towards the left side of the graph (towards the -10 side)
