# How do you graph the linear function f(x)=-2x+1?

See the explanation below.

#### Explanation:

First, the slope-intercept equation of a line is $y = m x + b$.

$b$ is the y-intercept, or the point where the line crosses the y-axis. In this equation, $b = 1$. You can plot this point on the y-axis.

Next, you know that the slope is $m = - 2$. Slope is basically $\frac{r i s e}{r u n}$, so you go down -2 units and move right 1 unit. Start at the point you already plotted (0,1) and plot each point from there.
