Hey guys, hopefully y'all can help me. I'm currently enrolled in a GEd school, got all the subjects passed but math, saved that for last because of this reason, need some help find table of values for equations, and some other stuff, but first things first, need to have 12 pages on this done by Monday, homework. I didn't even get one page yet. Here's the problems, I don't want you guys to do my work, please don't think that, I just don't know how to do it, teacher told me to plug it in and add or something totally forgot, thanks a lot. 2x + 5y = 10 y = 2/5x + 1 5x  4y = 20 Last edited by skipjack; July 23rd, 2018 at 12:09 AM.

You need to tell us what you are are supposed to do. 3 equations with 2 unknowns raises questions.

If so then pick a few x values and find out what the y's are. For example: x = 0 leads to y = (2/5)(0) + 1 = 1. So you have a point (0, 1). x = 1 leads to y = (2/5)(1) + 1 = 2/5 + 1 = 2/5 + 5/5 = 7/5. So you have a point (1, 7/5). etc. Get 6 points (or so), graph them, then connect the dots. Dan

All three expressions are straight lines. You need to find two points for each.
