Graphing Systems of Equations Mastery

In this video, Mr. Pasus introduces graphing systems of equations, demonstrating how to graph and interpret solutions. He covers three scenarios: intersecting lines with a single solution, parallel lines with no solution, and overlapping lines with infinite solutions. The video emphasizes understanding the graphical representation of systems and identifying solutions based on line interactions.

What is the first step in graphing systems of equations?

• Determine the y-intercept

• Calculate the slope

• Graph both equations on the same graph

• Find the x-intercept
