what graph is the graph of y ≥ 1 - 3x?

First of all option C and D are ruled out because no area is shaded. Because the values of Y are all ≥ 1 - 3x the area shaded should be above the line and the line should not be dotted, it should be a full line. Although there seems to be no option for both a full line and above the line is shaded.
Answer:
The graph of given equality is shown below.
Step-by-step explanation:
The slope intercept form of a line is
[tex]y=mx+b[/tex] .... (1)
where, m is slope and b is y-intercept.
The given inequality is
[tex]y\geq 1-3x[/tex]
The related equation of the given inequality is
[tex]y=1-3x[/tex] .... (2)
On comparing (1) and (2), we get
[tex]m=-3, b=1[/tex]
It means the slope of the line is -3 and y-intercept is 1. The graph of related line is a solid line because the sign of inequality is ≥.
Check the given inequality by (0,0).
[tex]0\geq 1-3(0)[/tex]
[tex]0\geq 1[/tex]
This statement is false. So, (0,0) is not included in the solution set.
Therefore, the graph of given equality is shown below.
