Problem

In Exercises 7-10, let A=(2,−1),B=(3,1),C=(−4,2)A=(2,-1), B=(3,1), C=(-4,2), and D=(1,−5)D=(1,-5). Find the component form and magnitude of the vector. 9. AC→+BD→\overrightarrow{A C}+\overrightarrow{B D}
Intuitive explanation

Vector addition combines displacements: first find each vector's components by subtracting starting point from ending point, then add them coordinate-wise. The magnitude is just the distance formula applied to the resulting vector. Think of it as: what single displacement gets you the same result as making both journeys?
