Quizplus · Accepted Answer

The distance between two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by the formula $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$. Substituting the given points, the distance is $\sqrt{(-8.6 - 3.5)^2 + (-5.7 + 4.3)^2} = \sqrt{(-12.1)^2 + (-1.4)^2} = \sqrt{146.41 + 1.96} = \sqrt{148.37} \approx 12.18$ units.
