Identify the boundary line equation

Using the Linear Functions knowledge point
\[

$$\begin{aligned} &\text{y-intercept: } (0, 5) \implies b = 5\\ &\text{x-intercept: } (1.67, 0) \implies \text{slope } m = \frac{0 - 5}{\frac{5}{3} - 0} = -3\\ &\text{Boundary line: } y = -3x + 5 \end{aligned}$$

\]

Determine the inequality sign

The boundary line is dashed, which means the inequality is strict (\(<\) or \(>\)).
The shaded region is below and to the left of the line.
Testing the origin \((0,0)\):
\[
0 < -3(0) + 5 \implies 0 < 5 \quad (\text{True})
\]
Thus, the correct inequality is \(y < -3x + 5\).
