Solving Quadratic and Linear Equations

Ryan Malloy from the Worldwide Center of Mathematics explains how to solve quadratic linear systems by graphing. The video covers graphing a quadratic equation y = x^2 + 2x and a linear equation y = -3x + 6, finding their intersection point in the first quadrant, and verifying the solution by substituting values. The tutorial highlights the benefits of graphing to visualize and solve such systems.
