If A and B are the points(-3,4) and (2,1) then the coordinates of the point C in AB produced such that AC=2BC are

Given,AC/BC=2, Draw a diagram,we can say that B is midpoint of A and C Use the midpoint formula Let coordinates of C be (x,y). Thus,according to midpoint formula,x-3/2=2 or x=7Andy-4/2=1 or y=6 Thus co ordinates of C are (x,y)=(7,6)
