Correct answer: D. and
- Read each boundary line (slope and intercept): The first boundary has slope and y-intercept , so its equation is . The second boundary has slope and y-intercept , so its equation is .
- Dashed means strict, solid means inclusive: The first boundary is drawn SOLID, so its symbol includes equality ( or ). The second boundary is drawn DASHED, so its symbol is strict ( or ).
- The shaded side gives the inequality direction: The region ABOVE is shaded, so that inequality is . The region BELOW is shaded, so that inequality is .
- Combine into the two-inequality system: A point is a solution only when it satisfies both inequalities, so the system graphed is and .
