The excluded values are the values that the variable cannot take on because it makes the overall expression undefined.
For example, we can't have in the expression because is undefined.
For both of these problems you do the same sort of thing, with some factorization along the way:
If or , the denominator is 0 and we have an undefined expression, so these are the excluded values.
If or , we get an undefined expression.
The answer of the slope is -½
use (y1-y2)/(x1-x2)
Lol that's so cool just give me the poonts
3(9b-4)
You divide each by 3 because of common factor you can message me for more math help if you need!!
