This is a region, there are an infinite number of answers.
First graph 5x+7y=57 It will be a dashed line because the less than sign is used.
then test a point (0,0) would be good.
If it satisfies the equation you shade in that side of the line, if it doesn't you shade in the other side.
Hope this helps.
