Question

Graph the inequality on a number line.

z>−10

To plot the inequality first choose the correct ray. Then select the location of the endpoint on the number line.

If you make a mistake, select the trash can and then select the ray that was graphed. You will then be able to start over.

Answer 1

z > −10

- Since the inequality is ">" (not "≥"), do not include −10: use an open circle at −10.
- Shade/point the ray to the right because greater numbers are to the right.

On a number line this looks like:

... −12 −11 ○(−10) → −9 −8 −7 ...

So select the ray that goes to the right and place the endpoint as an open circle at −10.
