Final answer:
Applying the distributive property to -8(y-1) results in -8y + 8 by multiplying -8 by each term inside the parentheses.
Step-by-step explanation:
Applying the distributive property to -8(y-1) involves multiplying -8 by each term inside the parentheses. This results in multiplying -8 by y and -8 by -1. Therefore, the distributive property gives us:
-8 × y = -8y
-8 × (-1) = +8
Combining these two products, the final expression is -8y + 8, which is option (a).
