Question Analysis
This question tests the student's ability to identify and write the equation of a boundary line for a given shaded region on a graph. The shaded region is formed by the intersection of two inequalities.

Key Concept Explanation
A system of inequalities consists of multiple inequalities that share the same variables. The solution to the system is the set of all points that satisfy all the inequalities simultaneously. The boundary lines are determined by converting the inequalities to equations.

Step-by-step Solution
1. Identify the first inequality:
2. Determine the slope and y-intercept of the second boundary line from the graph: The line has a slope of -1 and a y-intercept of 4.
3. Write the equation of the second boundary line:
