This is a circle with radius 3 and center at the origin. It is the locus of points 3 units from the origin.
In general, x² + y² = r²
is the equation of a circle with radius r and center at
the origin.

i might want to like to grant this a crack, yet regrettably, i'm previous due because that is. the way i might want to attitude it would want to be to construct a parabola using the concentration-directorix structure. you should use a vector equation for the directorix. change interior the coordinates of the criteria to get some circumstances for the variables interior the parabola's structure. with slightly of success, those circumstances will spit out an equation for the locus.

2^2+5=9
by distance formula
origin = 0
we get d= -1
i am sorry if it is wrong
