Answer 1

Step 1:

The system of inequalities .

The boundary of the graph is the graph of .

Since the inequality symbol is , the boundary line is dashed.

is greater than , so the region greater than is shaded.

Consider a test point as .

The statement is true.

Shade the inequality containing the point .

Step 2:

The boundary of the graph is the graph of .

Since the inequality symbol is , the boundary line is solid.

is less than or equal to , so the region less than is shaded.

Consider a test point as .

The statement is true.

Shade the inequality containing the point .

Graph:

Graph the inequality is .

 

Solution:

Graph the inequality is .
