Matt wants to go to an island located 20 meters below sea level. Fred wants to go to an island located 25 meters below sea level. When Matt drew a topographical map of the island, he indicated that his choice has a lower elevation than Fred’s choice.
Which of the following explains whether Matt’s map is accurate?
Matt is correct because -20 < -25. Therefore Matt’s island has a lower elevation than Fred’s.
Matt is incorrect because -20 > -25. Therefore Matt’s island has a higher elevation than Fred’s choice.
Matt is incorrect because -20 < -25. Therefore Matt’s island has a lower elevation than Fred’s.
Matt is correct because -20 > -25. Therefore Matt;s island has a higher elevation than Fred’s choice.
B) Matt is incorrect because
-20 > -25. Therefore Matt’s island has a higher elevation than Fred’s choice.

Points 𝑝 and 𝑞 are shown on the number line below
Determine if each expression is positive or negative and explain your reasoning.
a. 𝑝 + 𝑞
b. 𝑞 − 𝑝
a. Negative; 𝑝 is negative and 𝑞 is positive, so when they are added together, the sum will have the sign of the number with the greatest absolute value. Since |𝑝|>|𝑞|, then the sum will be negative. (Or equivalent; a demonstration with numbers that are accurate for 𝑝 and 𝑞 is also acceptable.)
b. Positive; 𝑝 is negative, so when 𝑝 is subtracted from 𝑞, then it is the same as adding the positive value of 𝑝 to 𝑞. Adding two positives gives a positive. (Or equivalent; a demonstration with numbers that are accurate for 𝑝 and 𝑞 is also acceptable.)
