**Coordinate geometry**

The study of geometry using the coordinate points is defined as Coordinate geometry. It is feasible to obtain the distance between 2 points, dividing lines in m:n ratio, calculating the area of a triangle in the Cartesian plane, finding the mid-point of a line, etc with the help of coordinate geometry.

**Cartesian plane**:

It comprises 2 perpendicular & directed lines whose intersection point is the zero point for both the lines. The horizontal line is termed as X-axis, and the vertical line is termed as Y-axis. The coordinate point (x, y) on the Cartesian plane describes that the horizontal distance of the point from the origin is x, and the vertical distance is y. If the x sign is positive, the point is on the right of the origin otherwise it is on the left. If y sign is positive, the point is above the origin otherwise it is below the origin.

**4 quadrants along with their respective values that are represented in the graph**

Quadrant 1 : (+x, +y)

Quadrant 2 : (-x, +y)

Quadrant 3 : (-x, -y)

Quadrant 4 : (+x, -y)

**Equation of a Line in Cartesian Plane**

(i) General Form: The general form of a line is given as Ax + By + C = 0.

(ii) Slope-Intercept Form: Assume x, y be the coordinate of a point through which a line passes, m be the slope of a line, and c be the y-intercept, then the equation of a line is given by y = mx + c

(iii) Intercept Form of a Line: Assume a & b be the x-intercept and y-intercept respectively of a line, the equation of a line is represented as y = mx + c
