x+y>2
y>2−x
Since y is always on the vertical axis,
unless you're like me and "cheat" when graphing inverses,
then the region above the line
y=2−x
contains all values of
y>2−x
since y=2-x on the line, y<2-x below the line and y>2-x above the line.
3x−2y<k
3x<2y+k
3x−k<2y
y>23x−2k
Same story, just fill in the blank for k.
The equations you specified are "linear", straight lines.
Hence the inequalities are relatively easy.
I also recommend you do what Mark asked,
otherwise I messed up his post.
