Let's see what this chapter is all about.

We learned about Coordinate Geometry in Class 10. In this chapter, we will

Revise our Coordinate Geometry concepts (Distance between points, Section Formula, Area of triangle) and solve some questions
What is slope of a line, and different methods to find it (angle, 2 points)
Finding angle between two lines using slope
Checking if lines are parallel or perpendicular, using slope
Proving three points collinear using slope (Slope of AB = Slope of BC)
Then, we study equation of lines
Equation of lines parallel to x and y axis
Slope of lines parallel to x and y axis
Equation of line when 1 point and slope is given
Equation of line when 2 points are given
Equation of line when slope and intercept is given(both x intercept and y intercept)
Equation of line when both x and y intercepts are given (Equation of line in intercept form)
Equation of line in normal form
General Equation of line, and converting any equation into General Form
Finding Distance of a point from the line
Finding Distance between two parallel lines
Distance of a point from a line along a line
