I want draw a line in SDL this is new to me so I am unsure of how to start.

Which version of SDL?

Are you planning on learning 3D graphics?

I found out how to draw a line, thx

Which method did you use to solve your problem?

I am working on a simple little tic tac toe game using sdl my only problem is how to implement the computer player

you can't implement minimax by drawing lines in SDL.

yes I know

Make it play at a random valid position at first, and improve from there.

Optimal play (as in, aiming for the shortest way to winning) is a solved problem, but it's so good that you have no chance at all (especially if it plays first). Thus I think it should play lass than optimal, for the player to have fun.
