The problem asks us to simplify the expression $(-7y)(-8)$.

1. Problem Description

The problem asks us to simplify the expression $(-7y)(-8)$.

2. Solution Steps

We need to multiply the two terms $-7y$ and $-8$. We can rewrite this as the product of the coefficients and the variable:

$(-7y)(-8) = (-7) \times (-8) \times y$

The product of two negative numbers is positive. Therefore, we have

$(-7) \times (-8) = 56$

Substituting this back into the expression:

$(-7y)(-8) = 56 \times y = 56y$

3. Final Answer

$56y$
