"1. If m+2=0;m=2
Sorry Ricky. But Sarah can still answer the question and can verify it with mine.
I wanted sarah to answer the question krassi
y-2x=4 ⇒y=2x+4 ⇒
What are the answers sarah? I don't.
I get it, I get it! :-D
First, off the bat you should recognize mx+y=2 and y-2x=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?
find the value(s) of m such that the equations mx+y=2, y-2x=4 have
