This math topic focuses on finding the intersection points of lines, specifically dealing with linear equations involving decimals and vertical lines. Participants practice calculating the intersection points between a linear equation expressed in slope-intercept form and a vertical line given as 'x=constant.' These problems enhance skills in substituting coordinates, handling decimals in equations, and understanding the graphical interpretation of linear equations. The topic is part of a broader introduction to linear equation intersections, catering to beginner-level understanding.
