2/(y - 9)
To determine where this is undefined, equate the denominator to 0. Your solutions will be where this is undefined.
y - 9 = 0
Therefore,
y = 9
The rational expression is undefined when y = 9.

1. m=6 2. r=3 3.y=0 just make the denominator = to 0 and it is undefined

A rational expression is undefined when the denominator is 0.
So here it is undefined when y-9 = 0, i.e. when y = 9.

un defined means denaminator must b zero;
so y-9=0
so
y=9
