$(1$ point$)$

Determine which differential equation corresponds to each phase line. You should be able to state briefly how you know your choices are correct.

$\frac{dy}{dt}=2y-y^2$

$\frac{dy}{dt}=y(y-2)$

$\frac{dy}{dt}=y^3-4y$

$\frac{dy}{dt}=y(2-y{)}^2$

$\frac{dy}{dt}=y^2-3y$

$\frac{dy}{dt}=3y-y^2$

$\frac{dy}{dt}=y^2|y-2|$

$\frac{dy}{dt}=4y-y^3$
