Question

Which number line shows point A at 3, point B at −1.5, point C at , and point D, which is the opposite of point A?

Answer 1

Explanation:

We have that point A is at 3.

This is 3 units to the right of 0 on the number line.

The point that is opposite of A should be 3 units to the left of 0.

That point will be at -3.

Therefore you have to choose the point that is on -3.

It should be similar to one in the attachment.
