Slope of line `zbar(a)+barzoverset(.)(a)+b=0, b in R ` is -A. `(-Re(a))/(Im(a))`B. `(-Im(a))/(Re(a))`C. `(Re(a))/(Im(a))`D. None of these

Answer» Correct Answer - A
`(x+iy)bara+(x-iy)a+b=0`
`rArr (bara+a) x + i(bara - a)y+b=0`
`:. m = (-(bara+a))/(i(bara-a)) = ((bara+a))/(i(a-bara))`
`:. M = (2.Re(a))/(i.2ilm(a)) = -(Re(a))/(Im(a))`
