Graphing Linear Equations: Key Concepts and Techniques

The video tutorial explains how to graph two systems of linear equations. It begins with graphing x=6 as a vertical line and then focuses on converting an equation to slope-intercept form. The process involves adding terms, isolating y, and solving the equation. The tutorial demonstrates graphing using the slope-intercept form and finding the point of intersection, which is x=6 and y=2.

What type of line does the equation x=6 represent?

• Diagonal line

• Vertical line

• Horizontal line

• Curved line

Why can't negative 18 and 2x be combined?

• They are constants

• They are coefficients

• They are not like terms

• They are like terms
