This math topic focuses on determining the equations of lines in standard form that are perpendicular to given lines. Questions require understanding how to identify slopes from standard form equations and applying the concept that perpendicular slopes are negative reciprocals of each other. Each problem presents a line equation, and students must select the correct equation from multiple choices that represents a line perpendicular to the given one.
