How do You Graph Linear Inequalities?

To graph linear inequalities, you would use the same technique as for a linear equation. You use graph paper, and label the x and y-axis. You substitute values for x in the equation to find values for y. Construct a chart of x and y values, plot them on the graph and you should get a line. Once you draw in the line (dotted or solid depending on the inequality), you can now shade the area denoted by the inequality. For example, the inequality y < x + 3 can be graphed by saying y = x+3. You find that the points ( 0, 3) and (-3, 0) are on this line. Plot these points. Because we have that this inequality is less thaa , we draw a dotted line and shade the area that is below the line.
