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.
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.
m1 = m2
x = a, where a is the x-intercept
y = b, where b is the y-intercept
The distance,d, between the points (x1,y1) and (x2,y2) is given by
The midpoint, M, between (x1,y1) and (x2,y2) is given by
