A system of equations with one solution will have lines that...

• are the same

• cross in one place

• are parallel and never touch

A system of equations with no solution will have lines that...

• are the same

• cross in one place

• are parallel and never touch

A system of equations with infinitely many solutions will have lines that...

• are the same

• cross in one place

• are parallel and never touch

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.
