ANSWER
(-2)(4)
EXPLANATION
We see from the number line that the product starts at 0.
It then takes 4 jumps backwards.
Each jump is 2 units.
Since it takes jumps of 2 units backwards (towards the negative side), we can say in other words that it takes 4 jumps of -2.
So, the product will be:
(-2) * (4)
(-2)(4)
