This topic focuses on practicing how to find the x-intercept of linear equations given in slope-intercept form. By setting the y-value to zero, users learn to solve for the x-coordinate where the function crosses the x-axis. The problems each present a different linear equation, and multiple choice answers are provided for students to select the correct x-intercept. This topic is an introductory part of a broader unit on line equations and graphing, helping students understand essential concepts in linear functions and graph interpretation.
