Consider AKLN drawn below. KL has equation L(-2:-1) K QUESTION 3 5x + 9, while KN has equation 5y +x-19 = 0. 3.1 Show that the coordinates of K are (-1;4). 3.2 Show that KLIKN 3.3 Hence or otherwise, determine the area of AKLN. 3.4 3.5 3.6 3.7 N(4:3) Determine the equation of the perpendicular bisector of LN. If L, N and P(7;y) are collinear, find y. Determine the coordinates of Q, if KLQN is a parallelogram. Explain, with geometric reasons, why KLQN is a square. ​
