Quizplus · Accepted Answer

The straight line distance between two points (x1, y1) and (x2, y2) in a coordinate plane can be found using the distance formula: $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$. For points (6,4) and (2,9), the distance is $\sqrt{(2 - 6)^2 + (9 - 4)^2} = \sqrt{(-4)^2 + (5)^2} = \sqrt{16 + 25} = \sqrt{41} = 6.40$.
