This math topic focuses on determining the negative inverse of integers and interpreting these results as fractions. It practices the concept crucial in understanding slopes and perpendicular lines, particularly when transitioning from integers to fractional expressions of slopes. This forms an introduction to slopes and perpendicularity in a broader unit that expands on line equations. Each question requires finding the negative reciprocal (negative inverse) of both positive and negative integers, and the answers are presented in fraction form to underscore the transition from integer to fraction.
