Laning against Jinx?

Hi guys.

So, yesterday I decided to play one (the fateful) last game. As you might've experienced as well, the "last" game is always the most challenging and never disappoints to cause some frustration. I was matched up against Jinx and Morgana with me as (you guessed it) Kai sa and my support being Lulu. My toplaner and midlaner weren't exactly winning their lanes but what frustrated me the most, was the fact that Jinx kept pressuring the lane constantly and I fell behind in farm very fast. It didn't help that Lulu used her q to poke the enemies under our tower and effectively hitting the minions with it. To top it off, the one time our jungler came and we managed to pick up a kill the enemy team's jungler pulled off a beautiful countergank and turned the situation around, which sealed the game for them. So, in this situation - what could I have done better? I wasn't really sure how to trade against Jinx, since she kept zoning me with her rocket launcher every time I tried to step up to farm. Additionally, Morgana pressured really hard. I wasn't ever sure to have the advantage in a trade and didn't trust in Lulu to have enough early game potential to turn the fight around.
