Best ResponseYou've already chosen the best response.0z is a complex number equidistant from (1,0) and (0,2) so it is a straight line perpendicular to the line joining both of them and passing through the mid point you will get the relation between y and x

Best ResponseYou've already chosen the best response.0I am confused. What do you mean by \(\mathbf{equidistant }\)?

Best ResponseYou've already chosen the best response.1let \(z=x+iy\) then the given equation is same as \[z1 = z2i\]

Best ResponseYou've already chosen the best response.1recall that z1 gives you the distance between \(z\) and \(1+0i\) and z2i gives the distance between \(z\) and \(0+2i\)

Best ResponseYou've already chosen the best response.1if you don't like that geometric thingy, you may work it algebraically : \[x+iy1 = x+iy2i\\~\\(x1)+iy=x+i(y2)\\~\\(x+1)^2+y^2 = x^2+(y2)^2\] simplify

Best ResponseYou've already chosen the best response.0I get \[y=\dfrac{2x}{4}+\dfrac{3}{4}\]. Is that right?

Best ResponseYou've already chosen the best response.0Why did: \[(x−1)+iy=x+i(y−2) \]Become\[ (x+1)^2+y^2=x^2+(y−2)^2\], Instead of\[ (x1)^2+y^2=x^2+(y−2)^2\]
