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

Which of the following linear equations has a y-intercept at (0, 2)?

• y = 2x

• y = x - 2

• y = x + 2

• y = 1 + 2x
