Where can I find books/resources on working with graphics (Pascal)?

Question

Books

I am a 9th grade student and soon some kind of remote programming competition will be held at my school (I don’t know for sure, since I will participate for the first time). There's something like a team tournament. Since I was one of the class got interested in programming since the beginning of the school year, the teacher invited me to participate in it. Well, I like learning to program and I agreed without hesitation. The guys who are with me in the team have been participating in such Olympiads for several years. I was told that every year a specific task is given for several hours (from 9 to 17). And "these tasks" are usually associated with writing a game. But I haven't worked with graphics yet. Not with graphics, not with objects. Therefore, I have a request to knowledgeable people: can anyone advise specific literature for this purpose? I really want to participate, but I won’t be dishonored very much).
