Recall the standard circle equation: \( (x - h)^2 + (y - k)^2 = r^2 \). Complete the square if the equation is expanded.
Desmos Tactical Shortcut: Plot the left-hand side and right-hand side as separate equations (e.g. \( y_1 = f(x) \) and \( y_2 = g(x) \)). Click the intersection points directly to read exact coordinates.
Alright, let's dive into this rigorous geometry and algebra crossover! We need to find the \( y \)-coordinate where a line through the origin is tangent to a specific circle. Step 1: Understand the shapes. The circle's equation is \( (x - 6...
