This math topic focuses on finding the negative inverse of a given slope, particularly transitioning from fractional slopes to negative integer slopes. The problems are structured to help understand how slopes of perpendicular lines relate as negative reciprocals. Each question presents a slope in fractional form and asks to determine its negative inverse. The options for answers include integers and decimals, facilitating practice in converting fractional slopes to their negative inverse in integer or decimal form. This is part of an introductory unit on slopes and perpendicular lines, which requires concepts of slope, fractions, and negative numbers.
