How do you do this? a) points (2,6), (-5,-1) and (-2,8) The equation of a circle has the form . Plugging in the coordinates (2,6), (-5,-1) and (-2,8) for (x,y), you get three equations for g,f and c: . . . . . Now write the three equations in matrix form and solve them by the usual reduction process.
Thanks... i can do those matrices.. if not i'll let you know..
