A student recieves a gift card an ice cream shop. The gift card has $35 on it, and each ice cream cone costs $4.50.

• The equation y =-4.5x + 35 represents the amount remaining on the gift card because the initial value of -4.5 is the cost per ice cream cone, and the rate of change of 35 is the amount of money originally on the gift card.

• The equation y =-4.5x + 35 represents the amount remaining on the gift card because the initial value of 35 is the amount of money originally on the gift card, and the rate of change of -4.5 is cost per ice cream cone.

• The equation y =4.5x + 35 represents the amount remaining on the gift card because the initial value of 4.5 is the cost per ice cream cone, and the rate of change of 35 is the amount of money originally on the gift card.

• The equation y =-4.5x + 35 represents the amount remaining on the gift card because the initial value of 35 is the amount of money originally on the gift card, and the rate of change of 4.5 is cost per ice cream cone.
