Solve Systems by Graphing, A.3F & A.3G

Multiple Choice

A system of equations with one solution will have lines that...

• are the same

• cross in one place

• are parallel and never touch

Multiple Choice

Use the graph to write a system of linear equations.  

• y = 4/3x -2
  y = -2/3x  +1
• y = -4/3x  - 2
  y = 2/3x  +1
• y = 4/3x  + 2
  y = -2/3x  -4
• y = -4/3x  + 2
  y = 2/3x  +1

Multiple Choice

When both lines in a system are identical, the system has __________________.

• infinite solutions

• one solution

• no solution

• parallel solutions

Multiple Choice

What is the solution to this system?

• (1, -1)
• (-1, 1)
• (0, -2)
• (2, 0)

Multiple Choice

Which system is shown on the graph?

• x - y = 4

  x + y = 2

• x + y = 4

  2x - 2y = 1

• x + y = -4

  x - y = 2

• x + y = 4

  x - y = -2

Multiple Choice

Which system is best represented by the graph?

• y = (1/2)x + 2

  x = -xy - 3

• y = 2x + 2

  y = -2x - 3

• y = 2x + 2

  y = -(1/2)x - 3

• y = (1/2)x + 2

  y = -2x - 3

Multiple Choice

What is the solution to the system?

• (3, -1)
• (2, -6)
• No Solution 
• (6, -2)

Multiple Choice

Which system is best represented by the graph?

• 2x + y = 1

  x - y = 2

• x + 2y = 1

  x - 2y = 2

• 2x + 2y = 1

  2x - 2y = 2

• 2x - y = 1

  x + y = 2

Multiple Choice

The graphs of two linear equations are shown. What is the best estimate of the solution to the system of linear equations?
