**Unlock the Problem**

Samantha interviewed shoppers at a mall. She asked them how many hours they had been at the mall and how much money they spent. She recorded their responses in the table.

Make a scatter plot to show the relationship between time at the mall and money spent.

Step 1: Write a title above the graph.

Step 2: Write ordered pairs that relate the amount of time to the amount of money.

(2, ____), (6, ____), (3, ____), (1, ____), (2, ____)

(2, ____), (5, ____), (4, ____), (1, ____), (3, ____)

Step 3: Choose a scale that is appropriate for the data on each axis. Then label each axis.

Since the data for the x-coordinates are all less than 10, use ___ for the x-axis.

Since most of the data for the y-coordinates are multiples of 5, use ___ for the y-axis.

Step 4: Graph the ordered pairs.

Answer:

The title of the above graph is Spending at the mall.

The ordered pairs that relate the amount of time are

(2,10), (6,35), (3,17), (1,10), (2,15)

(2, 18), (5, 25), (4, 20), (1, 5), (3, 15)

X-axis is the amount of time (hr)

Y-axis is the amount of money ($)
