Find the Equation
Hello everyone.. I need your help to solve this problem.
A point P(x,y) moves in such a way that its distance from (-2, 3) is 4. Find the equation.
Thanks

Re: Find the Equation
Based on the description, the path of the point is a circle. Use distance between two points formula.
$(x + 2)^2 + (y - 3)^2 = 4^2$
$(x^2 + 4x + 4) + (y^2 - 6y + 9) = 16$
$x^2 + y^2 + 4x - 6y - 3 = 0$
