This topic focuses on solving linear equations to find the x-intercepts. Students practice interpreting and manipulating equations in standard form (Ax + By = C) to determine where the line crosses the x-axis, which is arranged as multiple-choice questions. The coefficients and constants in these equations include decimal values, adding an additional layer of complexity to the arithmetic. This set of problems is part of a larger unit on line equations and graphing, helping to reinforce skills in algebra and coordinate geometry.
