Final answer:
The number not displayed on Jeremy's number line is -1. The other points correspond to -5/4 (-1¼), -3/4, 1/4, 3/2 (1½), and 2, which are all represented leaving -1 not plotted on the line.
Step-by-step explanation:
Jeremy is attempting to identify which number is not displayed on a number line that contains five rational numbers. The number line is divided into fourths, ranging from -2 to 2, and points are plotted at specific locations. By examining the descriptions of the points and comparing them with the options provided:
- One mark to the left of -1 corresponds to -1¼ or -5/4.
- Three marks to the left of 0 corresponds to -3/4.
- One mark to the right of 0 corresponds to 1/4.
- Two marks to the right of 1 corresponds to 1½ or 3/2.
- The point on 2 is simply 2.
Given these points, we can identify which of the provided options is not represented on the number line:
- Option 1: -1 (Not on the number line; the point to the left of -1 is -1¼)
- Option 2: 1/4 (Already on the number line).
- Option 3: -3/4 (Already on the number line).
- Option 4: -1/4 (Already on the number line).
Therefore, the number that is not displayed on Jeremy's number line is -1.
