Question

(4) The coordinates of the point dividing
the join of A(2, 1) and (-2, -1) in
the ratio 1:1 are​

Answer 1

Answer:

LET THE POINT BE P(X,Y)

X1= 2 , X2= -2 , Y1= 1 , Y2= -1

M1:m2 = 1:1 , which means that p is m.p of (2,1) and (-2,-1)

NOW , BY MID-POINT FORMULAE (SECTION FORMULAE)

Coordinates of P(x,y) = (2-2/2 , 1-1/2)

= (0/2 , 0/2)

= (0,0)
