I am burned out trying to understand analytical geometry

I wasted my whole secondary school just memorizing formulas and steps to solve problems but truly never understood what they mean and never tried to visualize it. Currently I am in high school and everything (analytical geometry) feels impossible. I don't understand what terms mean and what do I do next, almost every question is unique on itself and I really need concept to solve those. So today I decided to break studying like rats and I tried to understand concept and visualize problems. I learnt that slope is inclination and in equation y=mx+b, b is the value of y axis and to find x intercept I just needed to equate y = 0 since there is no y axis in x intercept. I studied that slope = 1 means every one step on right you go one step up, +ve slope means x intercept is negative and negative slope means x intercept is positive. I still get confused sometimes. I finally attempted a problem, I drew a circle and a line and tried to find point of intersection. And as you can see what nonsense I did in my textbook but couldn't find correct answer. Can you please guide me how to truly understand terms and topics of Analytical Geometry and how to visualize it? Suggesting any online resources or videos will be very helpful 🙏. Please ignore my bad graph.
