A florist is making bouquets of flowers for a wedding. Each bouquet will have 9 flowers. The graph shows the linear relationship between y, the number of flowers used, and x, the number of bouquets. The florist will use no more than 8 bouquets for the wedding. Which set best represents the domain of the function for this situation?

• F {0, 2, 4, 6, 8, 10}

• G {0, 1, 2, 3, 4, 5, 6, 7, 8}

• H {0, 18, 36, 54, 72, 90}

• J {0, 9, 18, 27, 36, 45, 54, 63, 72}

Two points are plotted on the grid. Which equation in slope-intercept form best represents the line that passes through these two points?

What is the equation in slope-intercept form of the line that passes through the points (-26, -11) and (39, 34)?

Which function represents this relationship?

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?

• c = 26.94c

• c = 18.99c + 7.95

• t = 26.94c

• t = 18.99c + 7.95

The graph of a linear function is shown on the grid. Which equation is best represented by this graph?

The conversion of degrees Celsius to degrees Fahrenheit can be represented by a linear relationship. The graph shows the linear relationship between y, the temperature in degrees Fahrenheit, and x, the temperature in degrees Celsius from the freezing point of water. Which equation best represents this situation?
