Ch 3 Test

Steffen graphed two lines in order to find the solution to a given system of equations.
What is the solution?

• (-3,-8)
• (-8,-3)
• (3,-8)
• (8,3)

• Infinite number of solutions

• (0, 7)

• (-5, -7)

• (5, 7)

What is the solution to the system?

• (2, -3)

• (-3, 2)

• (2, 3)

• (-4, 3)

• x

• y

• both

• neither

Using the elimination method, solve the system of equations. Write your answer as an ordered pair, (x,y). (NO SPACES)

Nancy went to the grocery story.  On Monday she purchased 4 apples and 6 bananas for a total of $13.  On Wednesday she purchased 3 apples and 7 bananas for a total of $13.50.  Which system of equations represents the situation?

• 4x + 6y = 3
  13.5x - 13y = 6
• x + y = 4
  x - y = 6
• 4x + 6y = 13
  3x + 7y = 13.5
• 4x - 6y = 13
  3x - 7y = 13.5

This system has an infinite number of solutions, TRUE or FALSE?

• TRUE
• FALSE

Which ordered pair(s) is a solution to the given system?

• (5,0)
• (1,-3)
• (3,3)

Which system of linear inequalities is represented by the graph?

• y≤2x-1
  y>-2x+3
• y>2x-1
  y≤-2x+3
• y<2x-1
  y≥-2x+3
• y≤2x-1
  y>2x+3
