This math topic focuses on identifying slopes that are perpendicular to given fractional slopes. It is part of a broader introduction to slopes and perpendicular lines. Each problem presents a slope in fractional form, and the task is to select a perpendicular slope from multiple choices, also presented in various formats (fractional, whole numbers). The main skill practiced is understanding the relationship between slopes of perpendicular lines, which involves negative reciprocals.
