Question

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

Answer 1

Given the equation `2x-4` is an equation of a line in the form `y=mx+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 `(x,y)` on the line.

For this line, our slope is `2`, and the y-intercept is `(0,-4)`

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.
