• Run off the graph
• Don't touch
• Intersect
• Exist

If a system of linear equations has one solution, what does this mean about the two lines? 

• Parallel lines
• the same line 
• Intersecting lines

If a system of linear equations has infinitely many solutions, what does this mean about the two lines? 

• Intersecting lines
• Same line
• Parallel lines

If a system of linear equations has no solutions, what does this mean about the two lines?

• Intersecting lines

• Same line

• Parallel lines
