The
point Q (ql , q2) is the image of the point P(p1, P2) on the line r
. (ai + bj) + c = O. Show that a(q2 - P2) - b(qt - PI) = 0, a(p1 +
ql) + b(P2 + q2) + 2c = O. Hence, express the coordinates of Q in
terms of Pl, P2, a, b, c and find the coordinates of the image of
the point (3,1) in the line r · (i + 2j) + 1 = O.
