The equation of a line is the first function that you learn about in grade 10 math. On this page you'll learn how to find the slope of a line, and how to find the x and y intercepts. We'll also show you how to graph linear functions, and find the equation of a line based on any information you might have. These pages cover most of the 'Lines' Unit in Math 10C. Slope of a Line Special Lines Lines on XY Axes Intercepts of a Line Quick Graphing Linear Equations Parallel & Perpendicular Lines Equation Forms Finding the Equation of Any Line NOTE: we'll be using the term 'line' throughout these pages, but sometimes will be showing line segments. You can assume that any illustration is always a line.
