(01.02 MC)Which number line shows the solution to −3 − (−1)? A number line is shown from negative 5 to 0 to positive 5. There are increments of 1 on either side of the number line. All the numbers are labeled on either side of the number line. An arrow pointing from 0 to negative 3 is shown. Above this, another arrow pointing from negative 3 to negative 4 is shown. A vertical bar is shown at the tip of the arrowhead of the top arrow. A number line is shown from negative 5 to 0 to positive 5. There are increments of 1 on either side of the number line.
