Question

Use a horizontal or vertical number line. Plot points at 7/10 and it's opposite. Label each point with it's value.

Answer 1

Assuming a vertical number line:

- Plot the point at 7/10 above the origin, between 0 and 1.

- Plot the opposite of 7/10 by reflecting it across the origin to the point at -7/10 below the origin, between 0 and -1.

- Label the point at 7/10 as "7/10" and the point at -7/10 as "-7/10".

The number line would look like this:
