Which system of equations does the graph represent?

• y = 1/3x + 3

  y = -5/3x - 3

• y = 5/3x + 3

  y = -1/3 - 3

• y = -4/3x + 3

  y = 1/3x - 3

• y = -5/3x + 3

  y = 1/3x - 3

Some students want to order shirts with their school logo. One company charges $9.65 per shirt plus a setup fee of $43. Another company charges $8.40 per shirt plus a $58 fee. Which equation represents the number of shirts when both companies charge the same amount?

• y = 9.65 + x
  y = 8.40 + x

• y = 9.65x + 43
  y = 8.40x + 58

• y =9.65x
  y = 8.40x

• y = 9.65x - 43
  y = 8.40x - 58
