Ex 7.1 , 1 Find the distance between the following pairs of points : (2, 3), (4, 1) Let the two points be P(2, 3) & Q(4, 1) We need to find distance PQ PQ = (( 2 1)2+( 2 1)2) Here, x1 = x coordinate of P = 2 y1 = y coordinate of P = 3 x2 = x coordinate of Q = 4 y2 = y coordinate of Q = 1 Putting values PQ = ((4 2 )2+(1 3)2) = ((2 )2+( 2)2) = ((2 2)+( 2 2) ) = (4+4) = 8 = (4(2)) = (4 (2)) = 4 2 = 2 2 = 2 2
