The talent show committee sold a total of 530 tickets in advance. Student tickets cost $3 each and the adult tickets cost $4 each. If the total receipts were $1740, how many of each type of ticket were sold?

• S + A = 530
  3S + 4A = 1740

• S + A = 530
  4S + 3A = 1740

• S + A = 1740
  3S + 4A = 530

• S + A = 1740
  4S + 3A = 530

Decide if the following statements are true or false about the graph.

Groups:

(a) True

,

(b) False

• The lines will not intersect, so the system has no solution

• The lines are perpendicular which means they will not ever cross.

• The line are parallel, so the system has no solution

• The slopes are equal, so the system has infinitely many solutions

• The slope(m) of the lines are equal

• The lines will eventually touch, so the system has one solution
