Chapter 8.3, Problem 1QCE

Match each differential equation with its slop filed.

$\begin{array}{l}\left(\text{a}\right)y\text{'}=2x{y}^2\text{\_\_\_\_\_}\\ \left(\text{b}\right)y\text{'}=e^{-y}\text{\_\_\_\_\_}\\ \left(\text{c}\right)y\text{'}=y\text{\_\_\_\_\_}\\ \left(\text{d}\right)y\text{'}=2xy\text{\_\_\_\_\_}\end{array}$
