Explain how to model the multiplication of –6 and 3 on a number line.

Answer 1

I don't know what your teacher expects, but I'd start at -6 and count 6 to the left three times.

Answer 2

Thanks

Answer 3

You're welcome.
But, starting at -6, we'd only need to count 6 to the left two times, not three times.

Or starting a 0 count 6 to the left three times.
