The given equation of the regression line is:
[tex]y=300.0397+2.829003x[/tex]It is written in the slope-intercept form:
[tex]\begin{gathered} y=mx+b \\ \text{Which can be rewritten as} \\ y=b+mx \end{gathered}[/tex]Where b is the y-intercept and m is the slope of the line.
As can be seen in the given equation, the slope m is 2.829003.
