- 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
