Answer 1

y=0.45x

Explanation:

• x = original price of ticket
  y = price of ticket with coupon
• coupon for 55% off the price of ticket (x-0.55x)

y = x - 0.55x can be simplified to y=0.45x

The line should only be in the first quadrant because the price of the tickets, or anything in general, can NOT be negative.
