1.
x-y+%3C=+3+
-y+%3C=+-+x+%2B+3+….divide both sides by -1
y+%3E=+x+-+3+.......for all x from 3 to infinity
or in interval [3,infinity)
so, shade that part on the graph

Graphing function y%3E=x-3:

graph%28+300%2C+300%2C+-10%2C+10%2C+-10%2C+10%2C+y%3E=x-3+%29



2.
x%2B2y+%3E=+6

2y+%3E=+-x+%2B+6
y+%3E=+-x%2F2+%2B+3.........for all x from -infinity to 6
or in interval (-infinity%2C+%7B%7B%7B6 }}}]
so, shade that part on the graph

Graphing function y%3E=-x%2F2%2B3:

graph%28+300%2C+300%2C+-10%2C+10%2C+-10%2C+10%2C+y%3E=-x%2F2%2B3+%29
