## FAQs on RD Sharma Class 11 Solutions Chapter 23 - The Straight Lines (Ex 23.7) Exercise 23.7

**1. What is the general equation of a straight line?**

If a,b and c are the constants, x and y are the variables and the slope is -a/b, the general equation of a straight line can be given as ax + by + c = 0. For example, 2x + 3y + 6 = 0 is a general equation of the straight line where 2, 3 and 6 are the constants, x and y are the variables and the slope is -a/b which in this case results in -⅔.

**2. What is the slope and y-intercept form of a straight line?**

A straight line that has a slope equal to tanθ, where θ is the angle formed by the given line with the positive x-axis and the y-intercept, say b can be given by y = mx + b, where m is the slope of the line.

**3. What is the slope point form of a straight line?**

A straight line that has a slope equal to tanθ where θ is the angle formed by the given line with the positive x-axis, and when it is passing through a point (x_{1}, y_{1}), the slope-intercept form of a straight line can be given by (y_{2} - y_{1}) = m(x_{2} - x_{1}).

**4. What is the best way to prepare for Class 11 Chapter 23?**

Students must study their notes obtained in class to prepare for the class 11 chapter 23 maths. Students can also use other online sources to understand the concepts given in the chapter. Vedantu is a wonderful online learning app for the students to clear their concepts about any topic and go all types of the study materials in the form of PDF, which is available free of cost.

**5. What is the intercept form of a straight line?**

A straight line which has x-intercept as ‘a’ and y-intercept as ‘b’ where point A is on the x-axis and point B is on the y-axis, is given in the intercept form equation by x/a + y/b = 1.
