When would we get "infinitely many solutions" to a system of equations?

• The lines are parallel, never intersecting

• The lines cross at one point

• The lines are the same and overlap at all points

• The lines cross at 2 points

When will we get "no solutions" from a system of equations?

• The two lines cross once

• The two lines are the same and overlap

• The two lines are parallel and never cross

• The two lines cross at 2 points

Match the following graphs to the systems of equations

• 
• 
• 

• 
• 
• 

2x + y = -3
x - 2y = -4

• (-2,1)
• (1,-2)
• (2,1)
• (1,2)

x = - 3
2x + 3y = 6

• (4,3)
