Best ResponseYou've already chosen the best response.1Okay good. distance between (1, 3) and P(x, y) : \(\sqrt{(x2x1)^2+(y2y1)^2}\) = 5 \(\sqrt{(x(1))^2+(y3)^2}\) = 5 \(\sqrt{(x+1)^2+(y3)^2}\) = 5 squating on both sides, \((x+1)^2+(y3)^2\) = 25

Best ResponseYou've already chosen the best response.0POINTS TO REMEMBER: A locus or curve is the set of points and only those points satisfying a given condition or a well defined property. This is the locus definition in geometry. Example of locus is provided below: (1) A,B are two fixed points. Let a set of points equidistant from A and B. Locus is the perpendicular bisector of AB . Every point on the perpendicular bisector of AB obeys the condition. (2) The locus of a set of points which are at a constant distance from a fixed point,is a circle.
