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

• They are parallel

• They are the same line

• They are intersecting once

• They are intersecting more than once

Parallel Lines never intersect because...

• they have the same slopes. 
• they have the same y-intercept.
• they have different slopes.
• they have different y-intercepts.
