Can I get some help please: I need a graph that matches this: 5x + 2y = 2 3x – 3y = 18

OpenStudy (anonymous):

plug 0 for x in first one (0,1) , plug 0 for y (5/2,0) connect the dot plug 0 for x in second one (0,-6) , plug 0 for y (6,0) connect the dot

can you take a look and tell me which one is correct? the first one or the second one?

OpenStudy (anonymous):

helloo..can you please take a look at my graphs? Thank you for your help

There are a couple of ways to answer this question. One way is to plot both lines (see imran's post). Another way is look at the graph, pick off a simple point, and see if that point's x,y works with either of the 2 equations.
