Ignore?
coordinate plane
A plan formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis.
perpendicular
two lines that intersect and form a right angle are
parallel
lines in the plane that are the same distance apart
Horizontal
Straight line across from side to side (length)
vertical
The direction of something that runs north to south or south to north.
quadrant
the x- and y-axes divide the coordinate plan into four regions. each region is called a ________________.
axes (plural form)
Lines of a graph that has two parts: the row (Y) and the column (X).
point
an exact location in space
coordinates
Are used to pinpoint where you are on a map or graph. They are also referred to as or Cartesian coordinates.
Cartesian coordinates
The idea of coordinates was developed by the mathematician and philosopher Rene Descartes who was also known as Cartesius, thus coordinates are named after its founder.
ordered pair
A pair of numbers that can be used to locate a point on a coordinate plane.
intersection
The graph of a compound inequality with "and" in which the solution is the overlapping or what is shared.
origin
The centre point of a number line (ground floor of a hotel, freezing point on a thermometer)
