Solutions by Graphing Systems

The video tutorial demonstrates how to use a graphing calculator to solve systems of equations graphically. It covers entering linear and nonlinear equations, adjusting the viewing window for better visibility, and using the intersect function to find points of intersection. The tutorial provides step-by-step instructions for both linear and nonlinear systems, highlighting the trial-and-error process of adjusting the viewing window and the use of the calculator's intersect function to find exact or approximate solutions.

What is the solution to the system of equations y = 3x - 4 and y = 7x + 2?

How do you enter the second function into the graphing calculator?

What should you do if the point of intersection is difficult to see on the graph?
