Sarah notices that her room's temperature is 4°F above the recommended temperature, and the downstairs bedroom's temperature is 4°F below the recommended temperature. She
graphs 72 and 64 on a vertical number line and determines they are opposites. Is Sarah
correct? Explain. (HELPPPPPP)
No, both temperatures are positive numbers and not the same distance from 0, so they cannot be opposites. Both numbers have to be the same distance from zero, but one has to be above zero and the other has to be below zero in order to be opposites.
