How to graph a inequality

Graph it like you would a normal equation except if it's not "equal to" it's a dashed line instead of solid line. Then shade the appropriate area on the graph,

for example ...

y > 2x + 1

is graphed as a dashed line y = 2x + 1 since it doesn't actually equal y.

y is greater than the line/equation so the area above is shaded where y is bigger
