The Number Line: Positive vs. Negative
A point starts at -2 on the number line. It moves five units to the right, then two units left, and finally one unit to the right. What number did the point end up at?
Incorrect.
Remember, negative numbers are to the left of 0 on the number line, and positive numbers are to the right of 0. This answer, -6, would be the answer if the left and right sides of the number line were switched.
Correct!
This diagram shows how the point moves, starting at -2.
After moving five to the right, the point is on 3. Moving two to the left, it ends up at 1. Finally, one unit to the right is 2.
Incorrect.
Don't forget to count 0 when you are counting on the number line. This answer, 3, would be the answer if you accidentally skipped from -1 to 1 when counting on the number line.
