First, set Y to 0 then solve for X 2X - 7 2X = -7 X = -7/2 Now plot (-7/2, 0) Then set X to 0 and solve for Y Y = -2(0) - 7 Y = -7 Now plot (0,-7) 1 = -2x -7 8 = -2x 8/-2 = x x = -4 Plot (-4, 1) I figured out this much, but cannot figure out how to get the graph. the original problem was to graph: 7.1x - 3.9y = 1.4 Help is appreciated. This is going on for quite a while and I really want to find the way to do this.Answer by Alan3354(30959)   (Show Source): You can put this solution on YOUR website!what does this look like in a graph after being plotted out?

This is going on for quite a while and I really want to find the way to do this. ---------------------- It's a straight line, so only 2 points are needed to graph it. 7.1x - 3.9y = 1.4 Set x = 0, solve for y, as you said, but I don't know where you get your numbers. at x = 0: 7.1*0 - 3.9y = 1.4 y = -14/39 --> (0,-14/39) ------------ at y = 0: 7.1x = 1.4 x = 14/71 --> (14/71,0) The 2 points are (apx) (0,-0.359) and (0.197,0)
