Systems of Equations Checking if Solution

The solution (x, y) to a system of equations is the point where they...? 

• Run off the graph

• Don't touch

• Intersect

• Exist

What is the solution to the system?

• (0, 3)

• (1, -1)

• (-3, 1)

• (1, 3)

Solve the following system by checking each answer choice. Remember you must "plug in" the x-value and y-value from the point into BOTH equations.

• (3, -1)

• (-1, -3)

• (-1, -1)

• (-1, 3)

Solve the following system by checking each answer choice. Remember you must "plug in" the x-value and y-value from the point into BOTH equations.

• (-4, 2)

• (4, 2)

• (2, -4)

• (2, 4)

Solve the following system by checking each answer choice. Remember you must "plug in" the x-value and y-value from the point into BOTH equations.

y = 1/2x + 2

y = -3x + 9

• (2, 3)

• (-2, -3)

• (3, 2)

• (-3, 2)

What is the solution to this system?

• (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. 

If a system of linear equations has one solution, what does this mean about the two lines? 

• Parallel lines

• the same line 

• Intersecting lines

What is the solution to the system?

• (3, -1)

• (2, -6)

• No Solution 

• (6, -2)

• (-8,-3)

• (3,-8)

• (8,3)
