Coordinate Geometry Formulas List for Class 9, 10 and 11
| All Formulas of Coordinate Geometry | |
|---|---|
| Slope Intercept Form of a Line | y = mx + c |
| Point-Slope Form | y − y1= m(x − x1) |
| The slope of a Line Using Coordinates | m = Δy/Δx = (y2 − y1)/(x2 − x1) |
| The slope of a Line Using General Equation | m = −(A/B) |
What are known coordinates?
Coordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D ). Cartesian coordinates , also called rectangular coordinates, have two or three straight-line axes that define the positions of points in 2D or 3D.
How do you find the coordinates of A and B?
You have to subtract 3 from A coordinate x which is 1,it will give you -2, and you have to subtract 1 from A coordinate y which is 1,it will give you 0. This will give us the coordinates of line AB. NOW we have to find the coordinates of B is by subtracting 3 and subtract 1 and it will give us (-5,-1).
What is coordinate geometry used for in real life?
It is also used to locate the position of aircraft in space. Coordinate geometry is also used in developing various games which specify the location of the object. Coordinate geometry is also used in describing maps that we see in our mobile phones and computers to locate the position.
What are ordinates in maths?
The ordinate in the coordinate system refers to the y coordinate of any point in a cartesian plane. It refers to the perpendicular distance of the point from the X-axis and is parallel to Y-axis. The ordinate gives the horizontal distance of a point from the origin.
How many numbers are in a coordinate?
A global address is given as two numbers called coordinates. The two numbers are a location’s latitude number and its longitude number (“Lat/Long”). Using Lat/Long is different from using a street address.
