Answer

The slope of the line $m=-2$ and its $y$-intercept is $(0,1)$

Work Step by Step

$f(x)=-2x+1$ Substitute $f(x)$ by $y$ for representative purposes: $y=-2x+1$ The equation of this line is now in slope-intercept form. This form is $y=mx+b$, where $m$ is the slope of the line and $b$ is its $y$-intercept. In this case, $m=-2$ and $b=1$ The slope of the line $m=-2$ and its $y$-intercept is $(0,1)$ The graph is shown below:
