Extra classes are no better than attending your daily classes. If you have a problem, you need to makes an effort to remove it. I would not suggest tutoring, but would ask you to try Algebra Buster. It will surely solve your problem concerning free linear inequality solver to a large extent.
I am most apologetic. I could have embedded the url our first time around: http://www.algebra-online.com/why-algebra-buster.htm. I don't acknowledge about a trial version, but the valid owners of Algebra Buster, unlike some resellers of cloned software, put up an entire refund warranty. Indeed, you can procure the legitimate edition, try the software program out and return it if one is not gratified by the performance and features. Even though I suspect you are going to cherish this software, I am very interested in learning from you should there be something for which it doesn't function. I do not need to advocate Algebra Buster for something it cannot do. But the next one discovered will probably be the first one!
I remember having often faced difficulties with function definition, y-intercept and parallel lines. A really great piece of math program is Algebra Buster software. By simply typing in a problem from workbook a step by step solution would appear by a click on Solve. I have used it through many math classes – Algebra 2, Basic Math and College Algebra. I greatly recommend the program.
