A marine biologist was interested in seeing the relationship of a baby manatee's weight and age. She gathered data and wanted to construct a graph to display the data in order to observe the change in weight per year.

Is a scatter plot or a line graph more appropriate to construct for the data, given the context of the problem? Explain.

A scatter plot, because it would show the association or relationship between two variables
A scatter plot, because it would show how a variable changes over time between each data point given
A line graph, because it would show the association or relationship between two variables
A line graph, because it would show how a variable changes over time between each data point given
