### Questions of Exercise 10.2 of Class 11 Maths

In the previous part of the chapter, you have learned some of the easiest concepts such as the value of (x₁, y₁) and (x₂, y₂) on the Cartesian plane that defines slope/ non-vertical or slanted line along with it you will study some of the important figures and its concepts such as figure given in NCERT book of 11th class. Class XI Maths exercise 10.2 is based on the concepts equation of line using slope and coordinate points.

#### Important Questions of Class 11 Maths Exercise 10.2

In class 11 Mathematics exercise 10.2, there are total 20 questions. Out of these, question number 15, 18 and 19 are considered as important one. The topic angles between the lines are the largest concepts explanation-wise as it includes case studies and examples too.

It is the last topic of the second part of chapter 10 from NCERT Solution for class 11th. After that you will study various forms of the equation of the line. There you will study what a line is and the condition that is being made to construct a line.

##### Concepts of Lines in Chapter 10 of 11th Maths

Paragraph before exercise 10.2 of NCERT Maths book states some of the figurative line concepts for which merely reading is not enough. The practice that you can do is make the line simultaneous while reading the statement given in the topic. The reason for suggesting such practice is that you need to make the figures in the question.

Secondly, some of the knowledge is abstract until you make it on paper which is preferably the best practice for mathematics. Unlike literature where most of the words are enough to explain the story, Maths requires solving.

###### Different forms of Equation of a line

So far you know that a line passes through different points irrespective of the fact of direction the line is moving. When with the help of mathematics you specify some of the points where the line passes through, you will get one special line. In this part, you will study different forms of equations that are the arbitrator for the points from which the line will pass.

The point-slope form, two-point form, slope intercept form, slope-intercept form and the normal form are such examples. Most of them are with the easy explanation except for the normal form. You might take example 11 into consideration as questions 2 to 8 in the exercise 10.2 are entirely based on these few concepts.
