NCERT Solutions for Class 11 Maths Chapter 10- Straight Lines

The Straight-line topic comes under the unit Coordinate Geometry which is included in the syllabus of the first term of class 11 for sessions 2021-22. This topic covers 10 marks out of 80 marks. This chapter contains 4 exercises by going through which students get clear concepts and command on the topic straight line. The concepts which are given in the solution of NCERT Maths Class 11 Chapter 10 are listed below:

1. Slope (m) for a non-vertical line.
2. When any line subtends an angle α in the positive direction of the x-axis, then the slope of the respective line is given by the equation, where
3. For a horizontal line, the slope is equal to zero and for a vertical line, the slope is undefined.
4. If the slope of the two lines is equal, then these are said to be parallel.
5. If the product of the slope of the two lines is equal to -1, then these lines are said to be perpendicular.
6. If the slope of AB = slope of BC, then the points are said to be collinear.
7. The horizontal line which is at a distance’ a’ from the x-axis, is either given by the equation or,
8. The vertical line which is at distance ‘b’ from the y-axis is either given by the equation or,
9. The line having slope m and the x, y coordinate axis represented by the equation
10. The line having slope m and y-intercept c is represented by the equation
11. The line having slope m and x-intercept d is represented by the equation
12. The line having ‘p’ as a normal distance from the origin and ‘ω’ as an angle between normal and the positive x-axis is represented by the equation
13. Any general linear equation or general equation of the line is of the form such that A and B are not equal to zero.

After going through the problems with solutions and solved examples in the chapter Straight line of Class 11 students gets a strong command on the topics, Shifting of origin, Slope of a line and angle between two lines, Equations of various types of the line like a parallel to the axis, point-slope form, slope-intercept form, two-point form, intercept form, and normal form, General equation of a line, equation of the family of lines passing through the point of intersection of two lines, the distance of a point from a line.
