Provide an appropriate response.Explain how you decide which half-plane to shade when you are graphing an inequality.
What will be an ideal response?
Use either method:
1) Solve for y; shade above if it uses
> or ?; shade below if it uses < or ?.
2) Choose a point not on line as test point. If
it satisfies the inequality, shade that region,
otherwise shade the other half-plane.
