Q
Q: If the position vector of point P is (3, -2) and Q is (1, 4), what is the vector PQ?
Solution:
Vector PQ = Q - P = (1 - 3, 4 - (-2)) = (-2, 6).
Steps: 8
Show Steps
Step 1: Identify the position vector of point P, which is (3, -2).
Step 2: Identify the position vector of point Q, which is (1, 4).
Step 3: To find vector PQ, we need to subtract the coordinates of point P from the coordinates of point Q.
Step 4: Write the subtraction for the x-coordinates: 1 (from Q) - 3 (from P).
Step 5: Calculate the x-coordinate: 1 - 3 = -2.
Step 6: Write the subtraction for the y-coordinates: 4 (from Q) - (-2) (from P).
Step 7: Calculate the y-coordinate: 4 - (-2) = 4 + 2 = 6.
Step 8: Combine the results from Step 5 and Step 7 to get vector PQ: (-2, 6).
