This math topic focuses on understanding how to determine lines with slopes that are perpendicular to given slopes. It involves calculating and recognizing the relationship between slopes of perpendicular lines—specifically, if one line has a slope \( m \), the line perpendicular to it has a slope of \( -\frac{1}{m} \). The problems present various decimal and integer slopes, and tasks students to identify the correct perpendicular slope from multiple choices, reinforcing their grasp of slope relationships and visual understanding of line graphs. This is an introductory level exploration within the broader context of slopes and perpendiculars.
