If the line 2x+5y=12 intersects the ellipse 4x2+5y2=20 in two distinct points A and B, then the mid point of AB is
The line 2x+y=3 intersects the ellipse 4x2+y2=5 at two points. The tangents to the ellipse at these two points intersect at the point
A straight line passes through points P (-2, 5) and Q (6, -3). It intersects the coordinate axes at points A and B. M is the midpoint of the segment AB. Find:
