You can put this solution on YOUR website! Graph the inequality:
first graph two lines, and
you need two points to graph each line
if ->=>point:(,)
if ->->=>point:(,)
second line
if ->=>point:(, if ->->=>point:(,
plot points and draw lines through:
since you need , left line on graph above should be dashed because that one is NOT part of solution, right line IS part of solution
your solution will be area between these lines including a line to the right (shade it), like this
