While exploring a glowing space station, Nova, Luna, and Emek discovered a giant number line leading to a locked portal called the Zero Gate. The gate would open only if they activated checkpoints in the correct locations. The checkpoints were labeled -6, -2, 0, 3, and 7. Starting at zero, they moved left to the negative integers and right to the positive integers, activating each checkpoint at its correct position. When the final checkpoint at 7 lit up, the Zero Gate opened, allowing the team to complete their mission.

Hint
The farther left on a number line, the smaller the integer.
Which checkpoint is farthest to the left on the Zero Gate number line?
-2-603Correct! -6 is the smallest number, so it is farthest to the left.
Compare the integers on the number line. The smallest value is farthest left.

Hint
Find the distance between -2 and 7 on the number line.
Starting at checkpoint -2, Emek moves to checkpoint 7. How many units does Emek travel on the number line?
Correct! Emek travels 9 units.
Count the distance from -2 to 0 and then from 0 to 7.

Hint
Negative numbers come before zero, and positive numbers come after zero.
Which list shows the Zero Gate checkpoints in order from least to greatest?
-2, -6, 0, 3, 7-6, -2, 0, 3, 7-6, 0, -2, 3, 77, 3, 0, -2, -6Correct! The integers are listed from least to greatest.
Arrange the integers from the smallest value to the largest value on the number line.
