Randy charges his tenants $400 each month to rent his houses plus $600 security deposit. In the new year, the property taxes increased on the area where he rents so as a result he must increase the rate of change by $25 to ensure his profits are not harmed. What equation best represents how much his tenants will now have to pay?

y = 425x + 600

y = 425 + 600x

y = 400x + 625

y = 400 + 625x

A local donut shop charged $6.50 for a dozen and provided a coupon in the newspaper for $1.50 off an order. Since the donut shop has gained popularity they have changed their coupon which now provides a discount of only half their original coupon's value. What is the equation that represents the value of a customer's order who uses the new coupon with their order?

y = 6.50x - 0.75

y = 6.50x + 0.75

y = 6.50x - 1.50 - 0.75

y = 5x - 0.75
