What is the y-axis in a scatter plot?

Back

The y-axis is the vertical axis that typically represents the dependent variable in a scatter plot.

Front

How can a trend line be used in a scatter plot?

Back

A trend line can be used to summarize the relationship between the variables and to make predictions about future data points.
