This document provides information about writing linear equations in slope-intercept form from a 7th grade pre-algebra textbook. It defines the y-intercept and x-intercept as the points where a line crosses the y-axis and x-axis. It also introduces slope-intercept form, where the equation of a line is written as y=mx+b, with m representing slope and b representing the y-intercept. Students are assigned examples and problems to work through relating to these concepts.
