Ok to graph y=1/2x-2, u know is the x-intercept so that is your starting point, now the 1/2 is the slope (m), which means 1 up and 2 to the right, so from that starting point you can go one up and two across, so on and so on. I think i know how to do the rest but I am not completely sure on them because I took math last semester.
