Graphing a Linear Inequality


Graphing a Linear Inequality


Step 1:-  Draw the graph of the straight line that is the boundary.

Make the line solid if the inequality involves ≤ or ≥; make the

line dashed if the inequality involves < or >.


Step 2:-  Choose a test point. Choose any point not on the line, and

substitute the coordinates of this point in the inequality.


Step 3:-  Shade the appropriate region. Shade the region that includes

the test point if it satisfies the original inequality; otherwise,

shade the region on the other side of the boundary line.
