Multiple Choice

Which system of inequalities matches the given graph?

• $$y>-x+3$$

  $$y\le\frac{2}{3}x-1$$

• $$y\le-x-3$$

  $$y>\frac{2}{3}x+1$$

• $$y<-x+3$$

  $$y\le\frac{2}{3}x-1$$

• $$y\le-x+3$$

  $$y>\frac{2}{3}x-1$$

Multiple Select

Multiple Choice

The Chess Club is selling brownies and lemon bars to raise money to travel out of state. They only have enough baking materials for no more than 200 brownies and lemon bars total, however, they need to make at least 630 dollars. If they sell each brownie for $4 and each lemon bar for $2.50, which system matches this scenario?

• $$b+l\le200$$

  $$4b+2.5l\ge630$$

• $$b+l>200$$

  $$4b+2.5l>630$$

• $$b+l\ge200$$

  $$4b+2.5l\le630$$

• $$b+l\le200$$

  $$4b+2.5l\le630$$

Multiple Choice

Which equation could pair with $$2y-x=7$$ to create a system with no solution?

• $$y=-\frac{1}{2}x+4$$

• $$y=\frac{1}{2}x+3$$

• $$y=2x-3$$

• $$y=\frac{2}{7}x+1$$

• You can use this Quizizz in coordination with your review packet for studying!

• The test questions are of similar difficulty, but this isn't everything.

• If something went poorly during the game, then do something about it!
