# How do you graph f(x) = 2x-4?

Given the equation $2 x - 4$ is an equation of a line in the form $y = m x + b$, where $m$ refers to the slope of the line, $b$ refers to the y-intercept, and $x$ and $y$ refer to any respective coordinate $\left(x , y\right)$ on the line.
For this line, our slope is $2$, and the y-intercept is $\left(0 , - 4\right)$
Now graphically, ever other point on the line is up by $2$ units and right by $1$ unit. You can see it on the graph below.
