Requiz Systems-Mixed Practice (Elimination Focus

Use the graph to write a system of linear equations

• y = x + 5

  y = x - 1

• y = -x + 5

  y = x - 1

• y = -x + 5

  y = x + 1

• y = -x + 1

  y = x - 5

Which statement best describes the solution set to the linear system

2x + 3y = 6

y = -2/3x + 18

• The lines intersect at one point so the system has one solution.

• The lines don't intersect at all because they are parallel so there is not a solution.

• The two lines are actually the same line so there is an infinite number of solutions.

• I don't understand the question and I wont respond to it (this choice is wrong).

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
