Advanced Problem-Solving in Coordinate Geometry 1. Intersection of Lines Problem: Find the point of intersection of the lines represented by: Solution:To find the intersection, solve the two equations simultaneously. From Equation 2: x=2y−5.x = 2y – 5. Substitute x=2y−5x = 2y – 5 into Equation 1: 2(2y−5)+3y=13.2(2y – 5) + 3y = 13. 4y−10+3y=13.4y – … Read more

“Coordinate Geometry”, which introduces the fundamental concepts of representing and analyzing geometric shapes in a two-dimensional plane using the Cartesian system

Key Concepts 1. Cartesian System The Cartesian system uses two perpendicular axes: Origin (OO): Intersection point of the axes (0,0)(0, 0).Points are represented as ordered pairs (x,y)(x, y), where: 2. Quadrants The plane is divided into four quadrants: 3. Plotting Points Example: Plot (2,3)(2, 3). 4. Distance Formula The distance between two points (x1,y1)(x_1, y_1) … Read more
