A passage from Houston to Brazil si a serious endeveaur and I'd only do it with an experienced crew. You have just started learning how to sail, so I'd say you still need a lot of time on the water before attempting something of this nature.
As pointed out, the prevalent wind on the NE coast of S. America is NW and the current also flows in thsi direction. Most cruisers go way offshore to make a loop and get favorable winds and current. This trip would take more than one month.
I'd suggest you take courses (Navigation, Bareboat) and do lots of sailing, help deliver boats, etc before attempting a trip like that.
