7. What integer is graphed on the number line?
I can't see the number line. Please upload the image or describe where the point is (for example, at 3, at -4, etc.), and I’ll identify the integer.

8. MP Use Tools
Strategy and tool: Use a number line (or a thermometer diagram) to compare -6 and -2. On a number line, numbers to the right are greater (warmer) and numbers to the left are smaller (colder).
Explanation and answer: -6 is left of -2, so -6 °F is colder than -2 °F. The temperature at 3 a.m. is colder by 4 °F (|-6 − (−2)| = 4).
