Step 2: Find X and Y intercepts
Place a graph using open or closed circles and be sure to label your graph!
Step 3: Determine proper line depending on inequality (solid or dotted line) and connect intercepts.
Step 4: Determine half plane shading
Check: Plug in ordered pair into the inequality and see if the statement makes sense
Heres a website that explains linear equations in 2 variables ,including what coordinates are, x and y intercepts, and quadrants.
