To explain: Taking check point where to shade when solving the inequalities.
Given information:
Suppose there are a system of inequalities.
Concept used:
Graph each inequality and then overlapping region is the solution of the system.
Dashed line is where in which strict inequality
Explanation:
Dashed line or solid horizontal where inequalities using in order to divide the coordinate plane for solution region.
Now taking any point to check whether the point satisfy or not .
Pick that checking point from the shaded region. if it satisfies then the inequality represent the half plane and shade that region which contains the points. If not shade the region the inequality does not contain that point.
So pick points from the shaded region.
