1.
Rectangular coordinate system/Cartesian coordinate system – two real number
lines that are intersected at 90 degree angles
2.
xaxis – Horizontal number line
3.
yaxis – vertical number line
4.
origin – the point of intersection of the x and y axes where both are equal to zero
5.
quadrants – The axes divide the plane into four quarters called quadrants
6.
ordered pair – each point in the rectangular coordinate system corresponds to an
ordered pair of real numbers (
x,y
)
7.
xcoordinate – the first number of each pair denotes the distance and direction
from the origin along the xaxis
8.
ycoordinate – the second number in each pair denotes vertical distance and
direction along a line parallel to the yaxis or along the yaxis itself
9.
variable – a letter or symbol used to represent an unknown quantity
10. constant – a known quantity
11. term – variables used in an equation
12. equation – formed when an equal sign is placed between two algebraic
expressions
13. equation in two variables – relationship between two quantities
