Question

Do the points shown represent additive inverses? Explain why or why not. Points are at negative 3 and positive 3.

Answer 1

Yes. The points represent additive inverses because an additive inverse is the opposite of a number and -3 is the opposite of 3.

Answer 2

The points on the number line do represent additive inverses. 3 and −3 are a zero pair, and when added they equal zero. The two numbers are the same distance from zero but in opposite directions.

The numbers are opposites of each other.

The numbers are the same distance from zero, but in different directions.

3 + (–3) = 0
