Solving Linear-Quadratic Systems Graphically (by hand, with integer solutions)

In this video, I show you how to set up and solve linear-linear and liner-quadratic systems graphically.

Please note that solving graphically by hand usually isn't the best strategy... good luck seeing 17/3 on the x-axis! But it's still an important skill to have in your "toolbox", since graphical interpretations are critical to your understanding of what functions are, and what it means to be a "solution" to a system of equations.

Realistically, you will usually use technology to solve by graphing, like Desmos online graphing calculator or, on standardized tests, maybe a graphing calculator.
