• y = -3/2x - 1

Printer ink costs $18.99 per cartridge. The company that sells the ink cartridges charges a flat rate shipping fee of $7.95, no matter the number of cartridges purchased in a single order. Which linear function models the total cost, t, for a single order of c cartridges?

• t = 26.94c

• t = 18.99c + 7.95

• t = 26.94c

• t = 18.99c + 7.95

• y = 2/3x - 5

• y = -2/3x + 2/3

• y = 2/3x + 5

• y = -2/3x - 2/3

A customer is ordering hats and T-shirts from an online store. Each hat costs $7, and each T-shirt costs $10. The customer receives free shipping if the amount of the order is over $100. Write an inequality that represents all possible combinations of hats, x, and T-shirts, y, in an order that qualifies for free shipping.

The tables of ordered pairs represent some points on the graphs of two different lines, Line a and Line b. Which system of equations represents the graph of these two lines?

• x - 6y = -90, x - 3y = 27

• x + 6y = 90, x + 3y = -27

• 6x - y = -15, 3x - y = 9

• 6x + y = 15, 3x + y = -9
