Question

If you move left 4 units and then right 9 units, what is your final position on a number line?

a) 13
b) 5
c) -5
d) -13

Answer 1

The final position on the number line after moving left 4 units and then right 9 units is 5.

Step-by-step explanation:

To find your final position on a number line after moving left 4 units and then right 9 units, you need to subtract 4 from 9. Moving left 4 units can be represented as -4 on a number line, and moving right 9 units can be represented as +9 on the number line. Therefore, the final position would be calculated as -4 + 9, which equals 5. Therefore, the correct answer is a) 5.
