Please find locus of z=at+b/t where a and b are complex constants and t is real. I started with a= a1+a2i and b=b1+b2i but stuck at x=a1t+b1/t, y=a2+b2/t how to eliminate t? so that I can get equation in terms of x and y only? Thanks in advance.

If x = at + b/t and y = ct + d/t, dx  by = (ad  bc)t and cx + ay = (ad  bc)/t. The product of those equations eliminates t.
