-10 -9 -8 -7 -6 -5 4 -3 -2 0 1 2 3 4 5 6 7 8 9 10
a. 9 + 13
b. 9 - 4
c. -4- 9
d. 9 - 13

Answer 1

The numerical expression represented by the number line is 9 - 13.

Step-by-step explanation:

The numerical expression represented by the number line shown is d. 9 - 13.

We can determine this by looking at the position of the numbers on the number line. The number line starts at -10 and goes up to 10, with the number 4 located in the middle. Since the number 4 is closer to the negative numbers, we know that the expression will involve a subtraction.

By subtracting a larger number (13) from a smaller number (9), we get a negative result that is to the left of 4 on the number line. Therefore, the correct choice is d. 9 - 13.
