From the given figure we can see a vertical line intersected the x-axis at point (2, 0)
Since the equation of the vertical line that passes through the point (a, b) is
Where a is the x-coordinate of any point on the line
Then the equation of the given line that passes through the point (2, 0) is
Since the line is solid and the shading area is right the line, then
The sign of inequality should be >=
Then the inequality that represented the line is
