2. The line segment joining the points A (2, 1) and B (5,–8) is trisected at the points P and Q such that P is nearer to A. If P also lies on line given by 2x – y + k = 0, find the value of k.

3. Find the ratio in which y-axis divides the line segment joining the points A(5,–6) and B(–1, –4).

4. Find the co-ordinates of a centroid of a triangle whose vertices are (3,–5), (–7,4) and (10,–2).

##### Questions from Board Papers

- If (3, 3), (6, y), (x, 7) and (5, 6) are the vertices of a parallelogram taken in order, find the value of x and y.
- If the distance of P(x, y) from the points A(3, 6) and B(–3, 4) are equal, prove that 3x + y = 5.
- If P(x, y) is any point on the line joining the points A(a,0) and B(0,b) then show that x/a + y/b = 1.
