Question

Given that P = (2, 9) and Q = (4, 14), find the component form and magnitude of vector PQ.

Answer 1

We are asked to determine the lengths of the line segment drawn with these points as endpoints. The equation of the distance between points is,
                              d = sqrt ((y2 - y1)² + (x2 - x1)²)
Substituting the coordinates of the points,
                               d = sqrt ((14 - 9)² + (4 - 2)²)
The numerical value for d is approximately 5.39.
