To compare: the graph of a linear inequality in two variables with the graph of a linear equation in two variables.
Explanation of Solution
Consider the linear inequality
Steps to graph the linear inequality:
Step 1: Graph
Step 2: Test
Step 3: Because
Graph of the linear inequality
Graph of linear equation
Comparison of the Graphs:
On the comparison of both graphs, there is a shaded area in the inequality graph which shows the solutions of the inequality lies in the shaded area.
Also, dashed lines is used which shows the points on the boundary line are not the solution of the inequality.
