1. The letter P on the number line below represents the number. (Use the hyphen for negative numbers and write answer as a decimal, such as –7.2)
Number line from negative 7 to positive 7 in increments of 0.5 is shown. Only the whole numbers are labeled. A point labeled P is placed at the thirteenth tick mark to the left of 0.
2. On the number line below, P represents a number. What is the value of the opposite of that number?
A number line from negative 4 to positive 4 in increments of 1 over 4, with all whole numbers alone labeled is shown. Put point P at the second tick mark to the right of 0.
A. 1
B. 2 over 4
C. negative 2 over 4
D. −1
3. Which of the following statements best describes the location of –(–6) on a number line?
A. It is 6 units to the left of 0.
B. It is 6 units to the right 6.
C. It is 6 units to the right of 0.
D. It is 6 units to the left of 6.
4. The number line shows the graph of an inequality:
A number line is shown from negative 5 to positive 5 with increments of 0.5. All the whole numbers are labeled on the number line. An empty circle is shown on the first mark to the left of 0. The region to the left of the empty circle is shaded.
Which statement explains whether –1.5 can be a value in the shaded region? (1 point)
a
Yes it can, because −1.5 lies to the left of –0.5
b
Yes it can, because −1.5 lies to the right of –0.5
c
No it cannot, because −1.5 lies to the left of –0.5
d
No it cannot, because −1.5 lies to the right of –0.5
5. The positions of two divers from the water's surface after a dive are shown:
Julie: –38 feet
Sue: –45 feet
Which inequality explains why Julie is closer to the surface than Sue? (1 point)
A. Because –38 > –45, so –38 is closer to 0 than –45
B. Because –38 < –45, so –38 is closer to 0 than –45
C. Because –38 > –45, so –38 is farther from 0 than –45
D. Because –38 < –45, so –38 is farther from 0 than –45
6. Amanda recorded the temperatures at which two oils freeze:
Oil Temperature
Olive oil –6.1 °C
Peanut oil 3.1 °C
Which statement about the temperatures at which these oils freeze is true? (1 point)
A. Peanut oil freezes at a lower temperature than olive oil because 3.1 °C < –6.1 °C.
B. Peanut oil freezes at a higher temperature than olive oil because 3.1 °C < –6.1 °C.
C. Peanut oil freezes at a lower temperature than olive oil because 3.1 °C > –6.1 °C.
D. Peanut oil freezes at a higher temperature than olive oil because 3.1 °C > –6.1 °C.
7. Laura and Jess observed two points, P and Q, on a number line.
A number line is shown from negative 2 to positive 2 with increments of 2 over 8. A point P is shown at the fifth tick mark to the left of 0, and a point Q is shown at the fifth tick mark to the right of 0.
Jess said that the absolute values of the numbers represented by the two points are different.
Laura said that the absolute values of the numbers represented by the two points are the same.
Which of the following explains who is correct? (1 point)
A. Jess, because the points are of different signs
B. Jess, because the points are at different locations
C. Laura, because the distance between the two points is 10 over 8 units
D. Laura, because each of the two points is 10 over 8 units from 0
