On a vertical number line, a point that is 10 units below 0 represents the number -10.
To find the same number on the horizontal number line, you should look for the point that represents -10.
Without the specific details or values shown on your horizontal number line, I cannot definitively tell you which point represents -10. However, if you have the options labeled as Point A, Point B, Point C, and Point D, one of these points must correspond to -10.
Please check the numerical values associated with each point and select the one that represents -10.
