For what values (cases) of the variables the expression does not exist: a/a−b (The equation is a fraction)

undefined at any point on the straight line b = a

Step-by-step explanation:                                 a

Your expression would be best written as   or as a / (a - b).

                                                                          a - b

This is undefined for a = b.  In other words, the expression is undefined at any point on the straight line b = a, as we cannot divide by zero.
