suppose that we are require to write equation of lines,whose go through origin and distance from point $F(-4,3)$ to this line is $1cm$
first of all ,distance from point $F(x_0,y_0)$ to line $A*x+B*y+C=0$ is $d={+,-}(A*x_0+B*y_0+c)/(\sqrt{(A^2+B^2)})$ because we have origin,we have $(x_0,y_0)=(0,0)$ equation of line is $y=k*x$ or $k*x-y=0$ if we put point $F(4,-3)$ ,i have got $K_1=-2/15*(6+\sqrt{6})$ and $k_2=2/15*(\sqrt{6}-6)$ or $y_1=-2/15*(6+\sqrt{6})*x$ and $y_2=2/15*(\sqrt{6}-6)*x$ is that correct or did i make some mistake?
