Match each vector field with its graph.

1. $\vec{F} = \langle x, y \rangle$

2. $\vec{F} = \displaystyle \left\langle \frac{x}{x^2+y^2}, \ \frac{y}{x^2+y^2} \right\rangle$

3. $\vec{F} = \langle -x, -y \rangle$

4. $\vec{F} = \displaystyle \left\langle \frac{-x}{x^2+y^2}, \ \frac{-y}{x^2+y^2} \right\rangle$
