The correct Answer is:
To find the coordinates of points P and Q where a line intersects the Y-axis and X-axis respectively, given that (2, -5) is the midpoint of PQ, we can follow these steps: ### Step 1: Define the Points Let the coordinates of point P (where the line intersects the Y-axis) be (0, y1) and the coordinates of point Q (where the line intersects the X-axis) be (x2, 0). ### Step 2: Use the Midpoint Formula The midpoint M of a line segment connecting two points (x1, y1) and (x2, y2) is given by: \[ M = \left( \frac{x1 + x2}{2}, \frac{y1 + y2}{2} \right) \] In our case, the midpoint M is given as (2, -5). Therefore, we can set up the following equations: \[ \frac{0 + x2}{2} = 2 \quad \text{(1)} \] \[ \frac{y1 + 0}{2} = -5 \quad \text{(2)} \] ### Step 3: Solve for x2 From equation (1): \[ \frac{x2}{2} = 2 \] Multiplying both sides by 2 gives: \[ x2 = 4 \] ### Step 4: Solve for y1 From equation (2): \[ \frac{y1}{2} = -5 \] Multiplying both sides by 2 gives: \[ y1 = -10 \] ### Step 5: Write the Coordinates of P and Q Now we can write the coordinates of points P and Q: - Point P (0, y1) = (0, -10) - Point Q (x2, 0) = (4, 0) ### Conclusion Thus, the coordinates of points P and Q are: - P = (0, -10) - Q = (4, 0)
