Where can I find books on the basics of graphics in terms of mathematics and geometry?

Question

Mathematics

I'm a 10th grade student, I'm a middle school student.
I write in OpenGL, I like it, but now I want to write my own low-level graphics system, with notes, like in OpenGL. But this requires a powerful mathematical knowledge base, where can one achieve this? In order to know a lot of things, from the Brazenham algorithm to perspectives.
What books would you recommend for my level? And preferably books that will help you reach a sufficient level of mathematics and geometry to start implementing my idea.
