Hello, can you help me find the slope for x=2-y

____
9 its 2-y over 9 I thought the answer was 2 but my professor said that's wrong. thanks

Rewrite x = (2-y)/9 as

9x = 2-y, and then change to the
"y = mx + b" form
y = -9x +2

The slope (m) is the coefficient in front of the x. In this case it is -9
