Cartesian Coordinate System is also known as __________ __________ ______
Rectangular Coordinate System
How is the Cartesian Coordinate System Constructed?
By drawing two number lines that are perpendicular to each other, and intersect at 0
What is the horizontal line called?
x-axis
What is the vertical line called?
y-axis
Together, the x-axis and y-axis are called?
Coordinate axes
What is the point of intersection of the coordinate axes called?
Origin
Where is the origin found?
(0,0)
What are the four quadrants?
QI, QII, QIII, and QIV
Which quadrant is (+,+)?
QI
Which quadrant is (-,+)?
QII
Which quadrant is (-,-)?
QIII
Which quadrant is (+,-)?
QIV
Apart from the four quadrants, these are the additional places in which a coordinate can be classified as. (State all four)
Positive x-axis
Negative x-axis
Positive y-axis
Negative y-axis
Good to Know!
QI = (2,5)
QII = (-2 5)
QIII = (-2,-5)
QIV = (2,-5)
Positive x-axis = (5,0)
Negative x-axis = (-5,0)
Positive y-axis = (0,5)
Negative y-axis = (0,-5)
