How do you determine the slope of a line in a scatter plot?

Back

The slope of a line in a scatter plot is determined by the change in the y-value divided by the change in the x-value between two points on the line.

What is the purpose of predicting values using a scatter plot?

Back

The purpose of predicting values using a scatter plot is to estimate the value of one variable based on the value of another variable.

Front
