Question

50 POINTS!!!!! Which inequality shows the relationship between the plotted points on the number line? An image of a number line indicating minus9, minus7, 0. A. –7 < –9 B. –9 < –7 C. –9 > –7 D. 7 < –9

Answer 1

Answer: The correct answer is B. –9 < –7. To compare negative numbers on a number line, you need to remember the following rules:

Begin at zero. For positive numbers, count to the right of zero. Positive numbers get higher the further to the right, eg 6 is greater than 3

For negative numbers, count to the left of zero. Negative numbers get lower the further to the left, eg -4 is less than -1

So, on the number line, -9 is to the left of -7, which means -9 is lower than -7. Therefore, -9 < -7.
