Which number is reached by moving 7 units to the right from −2 on the number line?

Answer and explanation

Correct answer: 5

Moving to the right on a number line means adding a positive number. Thus, −2 + 7 = 5, so the final point is 5. The option −9 incorrectly keeps a negative sign after adding the magnitudes, while 7 ignores the starting point. Exam tip: moving right increases the number, whereas moving left decreases it.
