Identify the type of growth in each table below as linear or non-linear.  

Linear growth forms a line when the data points are graphed. On a table, you can tell if growth is linear by checking if the -values increase at a constant rate

  1. x column 1 

    x column 2 

    x column 3 

    x column 4 

    x column 5 

    x column 6 

    y column 1 

    y column 2 

    y column 3 

    y column 4 

    y column 5 

    y column 6 

    When increases by , does increase by a specific amount? If it helps, take the data points and plot them on a graph.

    This table shows non-linear growth. does not increase at a consistent rate, and the points on the graph do not form a line.

  2. x column 1 

    x column 2 

    x column 3

    y column 3 

    y column 4 

    y column 5 

    y column 6 

    See the help for part (a).

    This table shows linear growth. Make sure you are able to explain why.
