Use the distributive property to write an equivalent expression.

-(8x-9)=

-8x + 9

To use the distributive property, you need to distribute the negative sign to each term inside the parentheses.

-(8x-9)

First, distribute the negative sign to the first term, 8x:

-8x

Next, distribute the negative sign to the second term, -9:

-(-9)

To simplify -(-9), you can rewrite it as 9 with the opposite sign:

9

Therefore, the equivalent expression using the distributive property is:

-8x + 9
