Best ResponseYou've already chosen the best response.0If you have to shade the required region, if it is y > something, then you shade above the line if it is y < something, shade below the line

Best ResponseYou've already chosen the best response.0The way I know to do this is to choose an ordered pair that is not on the line, like (0,0) in this case, and plug it into the inequality. If it makes the inequality true, then we shade that region. If it makes the inequality false, we shade the opposite region

Best ResponseYou've already chosen the best response.0The only thing that changes is that your line on the graph will be solid if you have the < or > sign with an = under it. Without the = under it, the line is a dashed line
