Solving a linear system of two equations by graphing

The video tutorial explains how to graph linear equations, focusing on vertical and horizontal lines. It addresses common student difficulties and demonstrates graphing using slope-intercept form and tables. The tutorial shows how to graph vertical lines where X equals a constant and horizontal lines where Y equals a constant. It concludes by finding the intersection of these lines, which represents the solution to the linear system.

What are the characteristics of vertical and horizontal lines when graphing linear equations?

Explain how to graph the equation X = -3 and what type of line it represents.

Describe the process of creating a table of values for graphing linear equations.

What does it mean when Y always equals a specific value in a linear equation?

How do you determine the solution point when two lines intersect on a graph?
