The video tutorial explains how to graph systems of linear equations using slopes and y-intercepts. It covers three possible outcomes: intersecting lines with one solution, parallel lines with no solution, and coinciding lines with infinite solutions. The tutorial provides step-by-step instructions for graphing each scenario, emphasizing the use of slope-intercept form and identifying key points on the graph.

What is the slope of the line represented by the equation y = -2/3x + 6?

• 2/3

• -2/3

• 3/2

• -3/2
