## List of Formulas in NCERT Solutions Class 11 Maths Chapter 10

NCERT solutions Class 11 maths Chapter 10 is a recognition of reaching a point in mathematics wherein we are now capable of using different branches of mathematics and see the beauty of how one translates into the other or how input from one branch of mathematics feeds into another stream of mathematics to unearth more information or patterns. Starting with the very building block, that is, a single point that can be mapped using the distance it has from two perpendicular axes. This lays the groundwork for an altogether new dimension where we are introduced to the next logical shape after a point that is of a line that can be defined by any two points on it. Equation of a line, its simplicity, and its completeness in defining the trajectory of a point is an important takeaway.

Some important formulas covered in NCERT Solutions for Class 11 maths Chapter 10 are given below:

**Slope of line passing through the points (x**_{1}, y_{1}) and (x_{2},y_{2}) : m = ( y_{2 }- y_{1}) /( x_{2}- x_{1})**Any point (x, y) with slope ‘m’ and y-intercept ‘c’ lies on the line if only y = mx + c.****Any line with slope ‘m’ that has x-intercept as ‘d’, in that case, its equation is y = m (x – d)****Equation of a line when it makes intercepts ‘a’ and ‘b’ on the x-and y-axis : x/a + y/b = 1**
