systems of equations

[Kortni]

how do you graph problems such as y=3x
4x+2y=30? I have to graph the system of equations and determine if they have no solution,one solution,or infinitely many. I do not understand how to graph this. Can anyone help please?

You should have learned about graphing lines long before receiving this exercise! If you need to review, there are tons of lessons on-line.

Use graph paper!

Feel free to reply with any specific questions that arise, while you study lessons on how to graph linear equations.

I just don't understand at all whatsoever how to graph these things!

So what do you expect: one of us to take a plane with graph paper, meet you and show you how?

solving systems of inequalities

Is there any way to solve a system of inequalities besides graphing? My problem is y>4x and y>-2x-3. Can anyone help me with this??
