Consider the Differential Equation $($DE$)($dy$)/($dt$)=-1-2$y$.$

a$.$ Sketch $($ie$,$ draw by hand$)$ a direction field for this DE$.$

b$.$ Without solving the DE$,$ determine $\backslash$lim$\_($t$->\backslash$infty $)$y$($t$)$ and briefly explain your answer. $($You will lose points if you solve the DE$).$
