A line equation can be written in slope intercept form, which is
[tex]f(x)=mx+b[/tex]Where m represents the slope and b the y-intercept.
The given line equation is
[tex]F(x)=-0.06895x+148.9[/tex]If we compare this equation with the slope intercept form, we have the following slope
[tex]m=-0.06895[/tex]
