Question 1.
Part A
At noon, the temperatures in New York City, New York, and Detroit, Michigan, had
opposite values. The temperature in Detroit was 6°C lower than in New York City. What
was the temperature in each city? Draw a number line to support your answer.

Solution

The number line has positive numbers to the right of zero and negative numbers to the left of zero. This means that numbers farther to the right are always greater than those to the left. In terms of temperature, the coldest temperature (the least number) is all the way to the left, and the warmest temperature (the greatest number) is all the way to the right.

We can now list the temperatures from coldest to warmest:

−7,−6,−2,−1,0,3,5

Sophia is incorrect. It is common for students to compare negative numbers as if they were positive and to assume that the one with the greatest magnitude is the greatest number. However, −23 is to the left of −14 on the number line, and so it is less than −14. Thus

−23<−14

and Anchorage was colder.

Again, the coldest temperature corresponds to the least number. So the warmest temperature corresponds to the greatest number. Since

−55>−89

the average temperature on Mars is warmer than the coldest temperature on Earth.
