Question

Which product is modeled by the number line below?

A number line going from negative 8 to positive 8. An arrow goes from 0 to negative 2, from negative 2 to negative 4, from negative 4 to negative 6, and from negative 6 to negative 8.


(negative 3) (4)

(negative 2) (4)

(2) (4)

(3) (4)

Answer 1

(B)(negative 2) (4)

Explanation:

The arrow on the number line ended at negative 8 (-8).

Given the options:

(A) (negative 3) (4) =(-3)(4)=-12

(B)(negative 2) (4) =(-2)(4)=-8

(C) (2)(4)=8

(D)(3)(4)=12

The expected product is -8 since that is where the arrow ended. Therefore, the product that is modeled by the number line is that which gives a result of -8. The correct option is B.

(B)(negative 2) (4) =(-2)(4)=-8
