Do you know how to graph an inequality?
helping my son with math homework and never seen so many letters in my life
You need to graph the line, like it was an =, then find out which side needs to be shaded. http://www.purplemath.com/modules/ineqgrph.htm
the options they give are (-1,-1) or (-2,-1) or (0,1) or (0,-2)
Well, if they give points, then what you can do is test them. Put in the x and y and see if it is true for both equations.
ok I thought so thanks
x-y>1 y <2x-1 Yah, so (-1,-1) \(x-y>1\implies -1-(-1)>1 \implies\) \(-1+1>1\implies 0 > 1\) Fails the first one, so don't bother with the second, and so on.
One of my favorite sites to look things up by topic: http://www.purplemath.com/modules/index.htm A site with amazing examples... but use Googles site search to find things on it: http://regentsprep.org/ (So in Google use site:regentsprep.org some search keys ) And the king of short, topical instuction. https://www.khanacademy.org/ Between those you should be able to learn ahead of your son for most things, and then just ask the remainder here.
Look at graping a linear inequality on Regentprep to see why I like it: http://regentsprep.org/Regents/math/ALGEBRA/AE85/GrIneqa.htm That is very easy to read, no junk on it, etc.
np. have fun!
