To model the graph of the solid line \( y = 2x - 4 \) with a shaded region above the line, you would want to express that \( y \) is greater than or equal to \( 2x - 4 \). This is because the shaded region above the line includes the line itself (as it's a solid line).
Thus, the correct inequality is:
\[ y \geq 2x - 4 \]
So, the correct response is:
y≥2x−4 (y greater than or equal to \( 2x - 4 \)).
