Scatter Plots Scatter plots are used when you want to represent data from a table. Match the data values in the table to the coordinates of the points on the scatter plot. Example # 2 : During the month of June, Sarah created a scatter plot that showed the hours worked and how much she earned in tips. If Sarah is working an 8 hour shift tonight, how much can she expect to earn in tips according to her scatter plot ? Hours Worked Tips earned ( $ ) 120

If Sarah is working an 8 hour shift tonight, how much can she expect to earn in tips according to her scatter plot ?

Example # 2 : During the month of June, Sarah created a scatter plot that showed the hours worked and how much she earned in tips Hours Worked Tips earned ( $ ) 120 Sometimes we will need to extrapolate the graph. That is, estimate the data past the known information.
