Describe geometrically the sets of points z in C defined by: Re(az + b) > 0 where a,b are elements in C (Complex set) I know how to do it if a,b were real numbers but in this case, it they were not. What can I do? Many thanks

Here is a hint to get you started. $\displaystyle \Re e (az) = \Re e(a)x - \Im m(a)y$
