### Important questions with answers of Coordinate Geometry Exercise 7.2

- If P (a, 4) is the midpoint of the line segment joining the points Q (-6, 5) and R (-2, 3), then find the value of a. [Answer: -12]
- A line intersects y –axis and x-axis at the points P and Q respectively. If (2, -5) is the mid-point of PQ, then find the coordinates of P and Q respectively. [Answer: (0, – 10) and (4, 0)]
- Find the rational number which the y – axis divides the segment joining (-3, 6) and (12, -3). [Answer: 1/4]
- Find the coordinates of a point A, where AB is diameter of a circle whose Centre is (2, -3) and B is (1, 4). [Answer: (3, – 7)]
- If A (-2, 4), B (0, 0), C (4, 2) are the vertices of a ΔABC, then find the length of median through the vertex A. [Answer: 5 units]
- Point P divides the line segment joining the points A (2, 1) and B (5, -8) such that AP: AB = 1:3. If P lies on the line 2x – y + k = 0, then find the value of k. [Answer: -8]
- Find the ratio in which the line 2x + 3y = 10 divides the line segment joining the points (1, 2) and (2, 3). [Answer: 2:3]
- Find the area of the triangle formed by joining the midpoints of the sides of the triangle whose vertices are (0,-1), (2, 1) and (0, 3). Find the ratio of this area to the area of the given triangle. [Answer: 1:4]
- Determine the ratio in which the point P (a, -2) divides the line joining of points (-4, 3) and B (2, – 4). Also find the value of a. [Answer: a = 2/7]
- If the point C (-1, 2) divides internally the line segment joining A (2, 5) and in the ratio 3:4. Find the Co-ordinates of B. [Answer: B (-5, -2)]
- Find the ratio in which the Y-axis divides the line segment joining the points (5, -6) and (-1,-4). Also find the coordinates of the point of division. [Answer: 5:1, (0, -13/3]
- Find the ratio in which the point P (x, 2) divides the line- segments joining the points A (12, 5) and B (4, -3). Also, find the value of x. [Answer: 3:5, x = 9]
