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?

• {0, 2, 4, 6, 8, 10}

• {0, 1, 2, 3, 4, 5, 6, 7, 8}

• {0, 18, 36, 54, 72, 90}

• {0, 9, 18, 27, 36, 45, 54, 63, 72}

The graph of a linear function is shown on the grid.

Which equation is best represented by this graph?

A construction worker built up to a home. The table shows the linear relationship between the height off the ground in inches and the number of steps.

What is the rate of change of height off the height off the ground with respect to the number of steps?

The water level of a river was measured each day during a two-week period. The graph models the linear relationship between the water level of the river in feet and the number of days the water level was measured.
