You can put this solution on YOUR website! he coordinate of a point P is twice the abscissa. this point is equidistant from (-3,1) and (8,-2) find the coordinates of P.
-----
P = (k,2k)
--------------------------
Distance from (-3,1):
sqrt[(k+3)^2+(2k-1)^2]
-----
Distance from (8,-2)
sqrt[(k-8)^2+(2k+2)^2]
---------------------------
Equation:
(k+3)^2+(2k-1)^2 = (k-8)^2+(2k+2)^2
--------------
Solve for "k" and "2k"
----------------
