What is the solution to this system?
y = 2x + 1
y = 4x - 1

Graph the 2 equations on the graph provided. You will put your answer into the next question.

What is the solution to the system in the previous queston. (Inpu your answer as an ordered pair)

What is the solution to this system?
2x - 3y = 6

y = -x + 3

Graph the 2 equations then provide your answer as an ordered pair by writing it on the graph.

What is the solution to the system in the previous queston. (Inpu your answer as an ordered pair)

What is the solution to this system?
y = 2x -11

y = 2x +5

Graph the 2 equations then answer the next question based on what you graphed.

Does the system have one, none or infinite solutions?

y = 2x -11

y = 2x +5

• One

• None

• Infinitely many solutions
