Answer 1

Answer:

1. If P(2.p) is the mid-point of the line segment joining

the points A(6, -5) and B(-2, 11), find the value

of p.

2. Find the value of k if P(4, -2) is the mid-point of

the line segment joining the points A(5k, 3) and

BC-k, -7).

3. Find the ratio in which the y-axis divides the line

segment joining the points (5.-6) and (-1,-4).

4. Find the fourth vertex of a rectangle whose three

vertices taken in order are (4,1), (7, 4) and (13,-2).

5. In what ratio does the line x - y - 2 = 0 divide the

line segment joining (3,-1) and (8,9)?
