The Straight Line

This topic provides the equation of a straight line parallel to x-axis and y-axis. We will come across the equation of a line passing through a fixed point and a slope is given. It also discusses the concept of intercepts here.

In this topic, we will learn how to reduce the general equation of a given line. It highlights the rule to reduce it to the intercept and normal form via solved examples. It also explains how to find the intersection of two straight lines.

This topic discusses the methods of finding the position of a point with respect to a line. It highlights position of two points relative to a line as well. It also covers the formulas used for solving questions.

In this topic, the concepts of intersection of lines are briefly explained. We will come across different conditions of intersection on the basis of coefficients of equations. We will also look into the method of approach via solved examples.

In this topic, we will learn how to find the perpendicular distance of a point from a line. It derives the formula to find the distance between two parallel lines. We will also come across various results based on this concept.

In this topic, we will come across the equation of the angle bisectors between lines. We will learn how to distinguish between bisectors of acute and obtuse angles here. It also explains the method of finding the bisector of the angle containing the origin.

In this topic, the family of lines is explained. We will study about the one parameter. It discusses the proofs of various equations which represent a line either parallel or perpendicular to the line.
