Answer:
The graph is a solid line, and the shading is above the line.
Step-by-step explanation:
Given
[tex]x + y \ge 1[/tex]
Required
Describe the graph of the inequality
We have:
[tex]x + y \ge 1[/tex]
Subtract x from both sides
[tex]y \ge 1-x[/tex]
The sign [tex]\ge[/tex] implies that the graph has a solid line
The sign [tex]\ge[/tex] which means greater than or greater also implies that the upper region is shaded
