I need help with Pre Algebra on graphing equations. Does anyone know any websites I can go to to get some help

No, you must use algebra to plot lines. How else would you explain the variables x and y?\n\nSlope-intercept form looks like this:\n\ny = mx+b\n\nOr, in the case of vertical lines:\n\nx = my+b\n\nWhere m is the slope and b is the x- or y- intercept, depending on which one you are using.

If you're taking the course through a bricks-and-mortar college, see if the college has math tutors available.  \nIf you're taking the course online or your school does not have tutors, there are websites online with free worksheets to help you with troubling concepts. Try one of the following or search google for "algebra help":\n\nhttp://www.algebrahelp.com/lessons/\nhttp://www.algebra.com/\nhttp://www.purplemath.com/\n\nIf it's really troubling you and worksheets just aren't cutting it, try purchasing a game from Best Buy or another computer store that focuses on Algebra skills.  They really do help.

If you can't get an answer here, try asking your Algebra teacher for extra help after school tomorrow.  It's sure to add to your grade that you asked for the help.

I will show one example on how to do it and then you take that example and apply it to the other two problems:\n\nOn the first problem, start with these two equations:\n2x-y+z=15\nx-y+2z=12\n\nTake the second equation and multiply it by -2:\n2x-y+z=15\n-2x+2y-4z=-24\ny-3z=-9\n\nLet's focus on the other part:\nx-y+2z=12\nx+2y-z=-3\n\nMultiply the second equation by -1:\nx-y+2z=12\n-x-2y+z=3\n-3y+3z=15\n\nLet's put those two equations together:\ny-3z=-9\n-3y+3z=15\n-2y=6\ny=-3\n\nPlug it into a y-value:\n-3-3z=-9\n-3z=-6\nz=2\n\nPut the y and z value into this equation:\nx-(-3)+2(2)=12\nx+3+4=12\nx+7=12\nx=5\n\n(5,-3,2)\n\nCheck:\n5-(-3)+2(2)=12\n5+3+4=12\n8+4=12\n12=12\n\nI hope that helps!\n\nP.S. I checked with the original equations and they equaled out also. You can check the answers with a graphing calculator. Whoever is giving the people for thumbs down for their answers, whether it is right or wrong, is being very unkind and rude for doing so. I am sure that I am not only person who does not appreciate the thumbs down given too.
