What do you need to know about Coordinate Geometry?
How to do it Simply!!!!!!!!!!!!!!!!!
slope formula
If the slope m of a line and a point (x1,y1) on the line are both known, then the equation of the line can be found using the point-slope formula: The slope of the line defined by the linear equation.
Distance formula
Definition of Distance Formula. The distance formula is used to determine the distance, d, between two points. If the coordinates of the two points are (x1, y1) and (x2, y2), the distance equals the square root of x2 − x1 squared + y2 − y1squared.
Midpoint formula
Definition of Midpoint Formula. Use themidpoint formula to find the midpoint between points (x1, y1) and (x2, y2). The formula is written as and is shown by: (that is, the average of the x-coordinates and the average of the y-coordinates).
