Question 367677
Use the distance formula,
{{{D^2=(x[2]-x[1])^2+(y[2]-y[1])^2}}}
Distance from (x,y) to (3,2),
{{{Z^2=(x-3)^2+(y-2)^2}}}
Distance from (x,y) to (0,y),
{{{W^2=(x-0)^2+(y-y)^2}}}
{{{W^2=x^2}}}
.
.
{{{Z=W}}}
{{{Z^2=W^2}}}
{{{(x-3)^2+(y-2)^2=x^2}}}
{{{x^2-6x+9+y^2-4y+4=x^2}}}
{{{highlight(y^2-4y-6x+13=0)}}}
