Learn about the slope, equation and properties of straight lines in a coordinate plane using algebra and geometry. Find formulas, examples and exercises on straight lines and their applications. A straight line is a line that is not curved or bent. All the basic and advanced concepts related to straight lines are covered here on this page. This lesson can also be downloaded as a PDF which helps students to refer to the concepts in offline mode. A line is a geometry body denoted by a zero-width body that extends infinity on both sides. A straight line is a line that has no curves. It can be horizontal, vertical, or inclined. If an angle is drawn between any two points on the straight line , then we will get a 180-degree angle. This article will cover topics like Straight lines, definition, Types of Straight Lines, Properties of Straight Lines, Equation of a Straight Line , General Equation of a Straight Line , Equation of Lines ... Learn how to write and graph the equation of a straight line in different forms, such as slope-intercept, point-slope and vertical. Find out the meaning of slope, y-intercept, rise and run, and see examples and exercises.
