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