 TOPICS This page: algebra distance-rate-time equations expressions linear relationships variables Linear Relationships Pre-Algebra students are introduced to linear relationships by plotting points that satisfy the equation on a coordinate grid and seeing how the points can be connected to form a line. Concepts of slope, equation of the line, and intersections of two lines (solving simultaneous equations) are covered at an introductory level.
