How do you graph a function? the question is  f(x) = 1/2 x - 2. but I would really like to know how to for other problems

Alright, that's in slope-intercept form. 1/2 is the slope and -2 is the y-intercept.
All you have to do is put in any value for x and graph two points based of the slope.
So lets make x=0 you'll graph (0,-2) and use the slope 1/2 to find the next point. Remember that the slope is rise (moving on the y-axis) over run (moving on the x-axis). So 1/2 means you go up a and over to the right 2.

I use the program geogebra for graphing, makes it a lot easier to do questions like this.
