Solve Systems of Linear Equations Using Graph

Solve the following system of equations by graphing:

• Infinite solutions

• (2, -2)

• (1, 0)

• (3, -4)

If a system of equations has no solution, what does the graph look like? 

• intersecting lines

• parallel lines

• skew lines

• intersecting lines

What is the solution?

• (1, -1)

• (-1, 1)

• (0, -2)

• (2, 0)

When you graph the exact same equation twice,

• you will have no solution. 

• you will have one solution.

• you will have infinite solutions. 

• you will graph a giraffe. 

Choose the 2 equations that are graphed and the solution to the system.

• (1, -2)

• (2, -1)

• (2, -2)

Solve the following system by graphing.  What is the solution?

• (1, 2)

• (-1, 2)

• (2, 1)

• (2, -1)

What are the solutions?

• x=1, y=-1

• x=-1, y=1

• x=0, y=-1

• x=1, y=0

Choose the 2 equations that are graphed and the solution to the system.

• (1, -2)
