Which boundary type is drawn for the inequality y < 2x + 1 and why?

• A. A dashed line, because the inequality is strict (<) and points on the line are not included.
• B. A dashed-and-solid hybrid line, because the y-intercept is an integer and integer intercepts require hybrid styling.
• C. A solid line, because all linear inequalities use solid lines unless stated otherwise in a separate instruction.
• D. A dotted line, because the slope is positive and positive slopes always use dotted lines.
