Brenda is going from (-4, 5) to (5,-4) but she needs to stop by the origin on the way. How far does she have to travel?

$$\text{the distance from (-4,5) to (0,0) is |(-4,5)| = \sqrt{(-4)^2+5^2} = \sqrt{41}}\\~\\ \text{Similarly the distance from (0,0) to (5,-4) is |(5,-4)|=\sqrt{41}}\\~\\ \text{So the total distance is the sum of these, d=2\sqrt{41}}$$
