# Coordinate Geometry - PowerPoint PPT Presentation

Coordinate Geometry. Quadrants of the Coordinate Plane. Co-ordinate plane is composed of x- axis and y-axis , which meet at the origin (0,0) Axes divide the plane into four parts called quadrants. Number line graphs Most basic type of graphing Usually used to graph inequalities.

### Coordinate Geometry

• Co-ordinate plane is composed of x- axis and y-axis, which meet at the origin (0,0)

• Axes divide the plane into four parts called quadrants

Example 1

1. Graph: x < 4

Solution: The problem asks you to graph all numbers

that are less than 4.

Solution: The problem, which is a conjunction, asks for a

graph of all thenumbers between -2 and 4. Be

sure to note that -2 is not included inthe solution

while 4 is.

• Example 2

• Slope of a line

• To find the slope of a line ‘m’ passing through points (x1,y1) and (x2,y2) :

• Two lines are parallelif their slopes, m1 and m2 are equal:

m1 = m2

• Two non parallel lines are perpendicular if their slopes are negative reciprocals of each other

m1*m2= -1

• Distance Formula

The distance,d, between the points (x1,y1) and (x2,y2) is given by

• Midpoint Formula

The midpoint, M, between (x1,y1) and (x2,y2) is given by
