Question 755169: I have x+3y-3=0. I figured out how to turn it into the correct equation of y=-1/3x+1. We are told to graph three points. We are given x= -3 for one point; x=0 for point two; and x=3 for third point. We then need to figure for the y-intercept with each of the three x-intercepts. I understand that the first one is (-3, 0); point two is (0, 1); and point three is (3, 2). However, my text shows me no math, therefore, I have no idea how they came up with the y-intercepts. My math on other problems like this end up with the wrong y-intercepts. I need to know how to do the math to get the correct y-intercept.
Thank you,
