Sam looked at two points that were graphed on a vertical number line. He saw the points −2 and 1.5. He wrote the following description:

"I am looking at a vertical number line that shows the location of two specific points. The first point is a negative number, so it is below zero. The second point is a positive number, so it is above zero. The negative number is −2. The positive number is 1/2 unit more than the negative number."
