Frequently Asked Questions
Coordinate Geometry (Analytical Geometry) is the branch of mathematics that represents points, lines, and shapes using numerical coordinates on a plane.
The Cartesian plane is a two-dimensional plane formed by two perpendicular number lines: the x-axis and the y-axis.
Coordinates are ordered pairs (x, y) that represent the position of a point on the Cartesian plane.
The x-axis is the horizontal axis on the coordinate plane.
The y-axis is the vertical axis on the coordinate plane.
The origin (0, 0) is the point where the x-axis and y-axis intersect.
Abscissa is the x-coordinate of a point.
Ordinate is the y-coordinate of a point.
The plane is divided into four quadrants numbered counterclockwise starting from the top-right region.
Quadrant I (+,+), Quadrant II (-,+), Quadrant III (-,-), Quadrant IV (+,-).
\( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \).
To find the distance between two points on the coordinate plane.
\( M = \left(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}\right) \).
It finds the exact center between two given points.
For a point dividing line segment in ratio m:n internally: ( P = \left(\frac{mx_2 + nx_1}{m+n}, \frac{my_2 + ny_1}{m+n}\right) ).
