3. What is Coordinate Geometry?

Coordinate Geometry is a branch of geometry in which a set of two numbers (Coordinates) is used to determine the position of a point with respect to two number lines that are mutually perpendicular to each other. The position of points come under coordinate and their links concerning various figures that come under the geometry section. Together, the position of points and their links or relations with various geometrical shapes or figures is termed Coordinate Geometry. The formula for the slope of a line is given as y = mx+c, where x and y are coordinates, c is constant, and m is the slope.

4. What is a cartesian plane?

A cartesian plane is also termed as a coordinate plane that two number lines that are mutually perpendicular to each other as well as intersect each other at their zero points making a right angle. The point of intersection is known as the origin. Out of two number lines, one is termed as a horizontal line or X-axis. And the other is known as the vertical line or Y-axis. The cartesian plane expands in all directions. In the cartesian plane, the right side is taken as positive and the left side as negative in terms of the x-axis. In the case of the y axis, the points above origin are positive, and the points below origin are negative.

5. What is a two-dimensional cartesian coordinate system?

A two-dimension cartesian plane is formed by the intersection of one vertical line and one horizontal line. The vertical line is referred to as Y-axis, and the horizontal line is referred to as X-axis. This coordinate system is known as a two-dimensional cartesian plane. The X-axis and Y-axis are perpendicular to each other and intersect at point O or the origin. These lines divide a plane into four sections called quadrants. A two-dimensional cartesian plane is also known as the XY plane.
