Step 1 :The question is asking to represent the given temperatures on a number line. The temperatures given are 3 degrees above zero, 2 degrees below zero, and 3 degrees below zero. These temperatures can be represented as 3, -2, and -3 on a number line.
Step 2 :The number line that matches the values of temperature given in the problem statement should have points at 3, -2, and -3.
Step 3 :\(\boxed{\text{The number line should have points at 3, -2, and -3.}}\)
