Question

which shows -1.5 graphed on the number line? (number lines as shown in the image)

Explanation:

Step1: Understand -1.5's position

-1.5 is between -2 and -1, since -2 < -1.5 < -1. It's halfway between -2 and -1.

Step2: Analyze each number line

• First line: Dot is between -3 and -2 (around -2.5), not -1.5.
• Second line: Dot is between -5 and -4 (around -4.5), not -1.5.
• Third line: Dot is between -2 and -1 (halfway, so -1.5), matches.
• Fourth line: Dot is between 0 and 1 (positive), but -1.5 is negative.

Answer:

The third number line (the one with the dot between -2 and -1)
