Answer: Last option.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope of the line and "b" is the y-intercept.
The slope of a line can be found with this formula:
In this case, knowing that this line goes through the points (0,3) and (2,-1), you get that its slope is:
By definition, a line intersects the y-axis when .
Since the line goes through the point (0,3), you can identify that:
Then, the equation of this line in Slope-Intercept form, is:
You know that everything to the left of the dashed line is shaded, then the symbol of the inequality is .
Therefore, the linear inequality that is represented by the graph is:
