Concise Selina Solutions for Class 10 maths Chapter 14 Equation of a Line


In math geometry, the lines and angles are essential tools. A line is a collection of points along a straight path; it extends in both the directions and has no endpoints. It has no definite length. Two lines are said to be parallel if they don’t have any intersecting points. Parallel lines do not meet. Two lines are said to be perpendicular if the angle formed between then is 900.

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept. The topics covered under this chapter are the basic concept of a straight line equation, the inclination of a line, the concept of slope (gradient), the slope of a straight line passing through two given fixed points, slopes of parallel and straight lines, various forms of the equations of straight lines and finding x/y -intercepts of a given line.
