equationfind the value(s) of m such that the equations mx+y=2, y2x=4 have #2 20051205 01:59:27
Re: equationFirst, off the bat you should recognize mx+y=2 and y2x=4 as equations of lines. Now, remember (or learn), that the "solution" to these equations is that line. That is, every (x, y) on that line will work out so that 0 = 0 when you plug it in. 1. When do two lines have no common solution? In other words, when do two lines share no points? 2. When do two lines share all points? And finally, 3. When do two lines share only one point? "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #4 20051205 02:17:24

Re: equationSorry Ricky. But Sarah can still answer the question and can verify it with mine. IPBLE: Increasing Performance By Lowering Expectations. #8 20051205 07:08:10
