The video tutorial explains how to solve systems of linear equations by graphing. It covers the possible outcomes when graphing two lines: intersecting lines with one solution, parallel lines with no solution, and coinciding lines with infinite solutions. The tutorial demonstrates graphing two lines, one in standard form and the other in slope-intercept form, and concludes with the lines coinciding, indicating infinite solutions.

What is the primary goal when solving a system of linear equations by graphing?

• To find the slope of each line

• To determine the x and y values that satisfy both equations

• To find the midpoint of the lines

• To calculate the area between the lines
