Question

A number line with arrows at both ends shows 0 labeled in the middle. Three tick marks are evenly spaced before and after the 0. Points upper A through upper E are plotted from left to right. Points upper A and upper B are to the left of 0 and are plotted in between the second and third tick marks. Point upper A is closer to the second tick mark to the left of zero. Point upper B is closer to the first tick mark to the left of zero. Points upper C through upper E are to the right of 0. Point upper C is in between 0 and the first tick mark. Point upper D is in between the second and third tick marks and and upper E is located after the third tick mark.

The following numbers are shown on the number line: −1.8 , 0.8, 3.1, −1.2 , 234 . Which number is represented by point B?

Answer 1

To identify which number corresponds to point B on the number line, we can analyze the description provided:

1. Point A is to the left of 0 and closer to the second tick mark on the left, which suggests it’s a number slightly greater than -2.
2. Point B is also to the left of 0 but closer to the first tick mark on the left, suggesting it’s a number slightly less than -1.

Based on the given numbers:

• -1.8 is less than -1 and fits the description of being between the second and third tick marks to the left of 0.
• -1.2 is closer to -1, which fits the description of point B being closer to the first tick mark.

Since point B is described as being closer to the first tick mark and hence a number greater than -1.8 but less than -1, the appropriate corresponding value for point B is:

−1.2

Thus, the correct answer is −1.2 (negative 1.2).
