• 
• 
• 
• 

How many solutions are there to the system in the graph?

• Three solutions

Solve the system of equations by graphing: y = x^2 - 4x + 3 and y = 2x - 1.

• Graphing is not a valid method for solving systems of equations

• The answer is 42

• This is a free response question and the answer will vary based on the specific points of intersection found on the graph.

• The solution is y = x^2 - 4x + 3 + 2x - 1

 $y=x^2-4$  

 $y=-x-2$  

Match the system of equations with its graph.
