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.
