Systems of Equations

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)
• (0, 1)

How many solutions does this system of equations have?

• One Solution
• No solution
• Infinitely Many Solutions
• Two Solutions

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

• Parallel lines
• the same line 
• Intersecting lines

Solve the system given:
3x - y = 7
2x + y = 3

• Infinitely Many Solutions

• One Solution

• Two Solutions

What is the number of solutions to the system of equations?

• No Solution

• Infinitely Many Solutions

• One Solution

• Two Solutions

3x + y = 12

• y = -3x +12
• x = y + 4
• x = y + 12
• y = 3x -12

Solve this equation for y:
 $-6x+3y=9$  

• y = 2x + 9

• y = 6x - 3

• y = 2x + 3

• y = 6x + 9
