For a system of differential equations:
$$ x'=x^2-1,\\ y'=-y $$
(1)Draw the solution curve that starts at the intial point $Y(0)=(x(0),y(0))$.
(2)For the above solution curve $Y(t)=(x(t), y(t))$, draw the $(t, y(t))$ graph.
Below is the slope field and my graph for (1)

I know the answer of the first one, it's a straight line from origin the the point $(-1,0)$, but I am not sure what's the second question is about.... Please help! Thanks a lot!
