You have to multiply -5 and 7y. So the answer is -35y. Also, it's the distributive property, not the associative.

You forgot to multiply by -1! And you're looking for the Distributive Property, not Associative.

Well, that's what the associative property is:
A * ( B * C ) = ( A * B ) * C
It allows you to move the parentheses like that when three numbers are being multiplied.
