Question

The winning times for the 200-meter dash can be approximated byF(x)= -0.06895x+148.9, where x is the yearWhat is the slope of F(x)?

Answer 1

A line equation can be written in slope intercept form, which is

`f(x)=mx+b`

Where m represents the slope and b the y-intercept.

The given line equation is

`F(x)=-0.06895x+148.9`

If we compare this equation with the slope intercept form, we have the following slope

`m=-0.06895`
