R(0, 16/7); 17.5 unit2
R(0, 16/5); 12.5 unit2
R(0, 16/5); 17.5 unit2
R(0, 16/7); 15.5 unit2
The line joining P(−4,5) and Q(3,2) intersect the y-axis at point R .PM and QN are perpendicular to P and Q on the x- axis. Find:
(1) the ratio PR:RQ.
(2) the coordinate of R.
(3) the area of the quadrilateral PMNQ.
The perpendicular distance of a point P from x-axis is 4 units and the perpendicular distance from y-axis is 5 units(assuming in the positive direction). What are the coordinates of P?
