I'm trying to add the equation for a linear regression line to a scatter plot that I have made. I first plotted my data points then used the polyfit function to add a first-order line to my plot. Now I want the equation of the line in y = mx + b form to...

A scatter plot is a chart that displays the values of two variables as points. The data for each point is represented by its position on the chart.
SCATTERPLOT的最小指定项是一对括号中的变量。 没有缺省规范。 您可以根据需要在括号中指定任意数量的变量对。 在每组括号中指定的第一个变量沿着垂直轴绘制,第二个变量沿着水平轴绘制。 绘图符号用于表示在同一位置出现的多个点。 可以指定在VARIABLES子命令中指定的任何变量。
