Is the point (3, 1) a solution for the following inequality? Choose the best answer that has the best explanation.

• Yes because it is located in the shaded region.

• No because it is located on the line and the line is dotted.

• Yes because it is located on the line.

• No because it is in the shaded region.

There are 15 animals in a barn.  These animals are horses and chickens.  There are 44 legs in all.  Which system of equations represents the situation?

• x + y = 15
  4x + 2y = 44

• 4x + 2y = 15
  x + y = 44

• x = 2y + 44
  4x = y + 15

• 2x - 4y = 44
  x - y = 15

Find the slope

Dustin wants to buy 9 tickets to the circus. The lower balcony tickets cost $20.95 while the upper balcony tickets cost only $12.50. How many of each type of ticket did Dustin buy if he spent $146.30?

• 4 lower balcony tickets, 5 upper balcony tickets

• 5 lower balcony tickets, 4 upper balcony tickets

• 6 lower balcony tickets, 3 upper balcony tickets

• 3 lower balcony tickets, 6 upper balcony tickets

A sporting goods store sells left haded (x) and right handed (y) gloves. In one month, 12 gloves were sold for a total of $561. Right handed gloves cost $45 each and left handed gloves cost $52. Which system could be solved to determine the number of each type of glove sold?

• x + y = 561
  45x+52y=12

• x + y = 12
  52x+45y=561

• x + y = 12
  45x+52y=561

• x + y = 561
  52x+45y=12
