This math topic focuses on identifying the equations of lines that are perpendicular to given lines in slope-intercept form. It primarily teaches how to determine the slope of a line perpendicular to another by using the negative reciprocal of the given slope. Each question presents a linear equation and asks the student to choose the correct perpendicular line from a set of options. This skill is fundamental in understanding the relationships between slopes of perpendicular lines in coordinate geometry.
