Which number sentence does the following number line represent?

siniylev [52]

Answer:

Last option: $3+(-7)=-4$

Step-by-step explanation:

The number line can help us to make additions and subtractions.

To add a positive number we need to move the point to the right and to add a negative number we need to move the point to the left.

You can observe in the figure that the point on the number line is moved from 3 to -4, then it is moved 7 places to the left. Therefore, you can express it in the following form:

$3+(-7)$
