ANSWER
[tex]y \geqslant \frac{1}{4} x - 1[/tex]
EXPLANATION
The graph has a solid boundary line.
The region above the boundary line is shaded
Therefore the inequality sign involved is '≥'
The boundary line has equation
[tex]y = \frac{1}{4} x - 1[/tex]
We can now conclude that, the inequality graphed above is
[tex]y \geqslant \frac{1}{4} x - 1[/tex]
