To understand why the correct linear inequality based on the graph is y ≤ -2x + 9.99, let's break down the elements involved:

Identifying the Line:
The inequality involves a line with the equation y = -2x + 9.99.

Interpreting the Inequality y ≤ -2x + 9.99:
The inequality symbol ≤ indicates that y can be less than or equal to the values on the line y ≤ -2x + 9.99.
Graphically, this means the region of interest is the area below the line, including the line itself. So it must be a solid line instead of a dashed line.

Shaded Region:
In the graph, if the area below t...
