Coordinate Geometry
Class 11 Coordinate Geometry is a branch of mathematics that deals with the study of geometric figures using a coordinate system. In this subject, students learn how to represent points, lines, curves, and shapes on a coordinate plane using numerical coordinates. The Cartesian coordinate system, developed by Rene Descartes, is commonly used in coordinate geometry. It consists of two perpendicular number lines called the x-axis and the y-axis, which intersect at a point called the origin.Key concepts covered in Class 11 Coordinate Geometry include:
Cartesian Coordinates: Students learn how to represent points in a plane using ordered pairs of numbers (x, y), where x is the distance along the horizontal x-axis and y is the distance along the vertical y-axis.
Distance Formula: Students learn how to calculate the distance between two points on a coordinate plane using the distance formula, which is derived from the Pythagorean theorem.
Midpoint Formula: Students learn how to find the midpoint of a line segment between two points on a coordinate plane using the midpoint formula.
Slope of a Line: Students learn about the concept of slope, which measures the steepness of a line. They also learn how to calculate the slope of a line using the rise over run formula.
Equations of Lines: Students learn how to write equations of lines in different forms, such as slope-intercept form, point-slope form, and standard form.
Parallel and Perpendicular Lines: Students learn how to determine if two lines are parallel or perpendicular based on their slopes.
Conic Sections: Students learn about conic sections, which are curves formed by the intersection of a plane and a double-napped cone. The main types of conic sections include the circle, ellipse, parabola, and hyperbola.

Question 1: Plot the following points on the graph paper:
(i) (2,5) (ii) (4,-3) (iii) (-5,-7) (iv) (7,-4) (v) (-3,2)
(vi) (7,0) (vii) (-4,0) (viii) (0,7) (ix) (0,-4) (x) (0,0)
Solution :
Question 2: Write the coordinates of each of the following points marked in the graph paper.
Solution:
| Point | Distance from the y-axis (units) | Distance from the x-axis (units) | Coordinates of Point |
| A | 3 | 1 | (3,1) |
| B | 6 | 0 | (6, 0) |
| C | 0 | 6 | (0, 6) |
| D | -3 | 0 | (-3,0) |
| E | -4 | 3 | (-4,3) |
| F | -2 | -4 | (-2,-4) |
| G | 0 | -5 | (0,-5) |
| H | 3 | -6 | (3,-6) |
| P | 7 | -3 | (7,-3) |
| Q | 7 | 6 | (7,6) |
The explanation for Coordinates of A:
The distance of point A from the y-axis is 3 units, and from the x-axis is 1 unit. A lies in the first quadrant, so both the coordinates are positive. This implies that the coordinates of A are (3,1). Similarly, other points are, A (3,1), B (6,0), C (0,6), D (-3,0), E (-4,3), F (-2,-4), G (0,-5), H (3,-6), P (7,-3), Q (7,6)RD Sharma Solutions for Class 9 Maths Chapter 11 Coordinate Geometry Summary
