ok it would be a straight line in the beginning
If by "straight line" you mean one that is flat (horizontal), then yes. What I've been hinting at and trying to get you to realize since my first reply to you is that a constant velocity appears as a flat line on a graph of velocity vs. time. I hope that much is obvious.

from somewhere above 0m/s
Yes, the level would correspond to whatever the initial constant velocity was.

and then would it go into a straight line down towards 0 after the brakes go out.
Right (except that I think you mean after the
engine goes out). Do you know what the slope of this line is? (Hint: what is the only force acting on the go-kart after the engine goes out)? Granted, you don't need this information for a sketch, but I just want to see if you understand what is happening.

sorry I'm having troubles being interested in this physics work because I'm only taking it to raise my high school average by .2% so I can major in finance.
An apology to
me is unnecessary (I don't really care how motivated you are). But I should point out that (1) this is an extremely basic physics problem that you should be able to do yourself by applying the concepts that you've been taught in class, and (2) if you want to major in finance, then understanding how to represent data and equations
graphically will be an essential skill.
Even setting that aside, your comment doesn't make much sense as an excuse. If you want to
raise your average by taking this course, then you are going to have to do
really well in it, which would seem to me to be all the more reason to pay attention to the assignments (even if you don't find the subject matter inherently interesting).
