Yes, a.
The correct statement that explains how to use a number line to determine the number that is 3 less than -4 is A. Go to -4 on the number line and then move 3 units to the left.
To use a number line, you start by locating the number -4 on the number line. Since -4 is a negative number, you move to the left of the origin (0) on the number line. Once you locate -4, you need to determine the number that is 3 units to the left of -4. Moving 3 units to the left means you move in the negative direction on the number line. So, from -4, you would move 3 units to the left, which brings you to the number -7. Therefore, the number that is 3 less than -4 is -7.
