Coordinate Plane Basics

plane

• Flat surface

• Curved surface

• Solid object

• Irregular shape

x-axis

• The vertical axis on a coordinate plane that displays the second number of an ordered set

• The horizontal axis on a coordinate plane that displays the first number of an ordered set

• A line that represents the slope of a graph

• The axis that indicates the direction of the graph

ordered pair

• A pair of numbers used to locate a point on a graph (x,y)

• A single number representing a value on a graph

• A set of three numbers used for 3D coordinates

• A pair of letters used to denote variables

origin

• (0,0) Intersection of the x and y axes. Center of the coordinate plane.

• (1,1) Point where the x-axis and y-axis meet.

• (0,1) The point on the y-axis where it intersects with the x-axis.

• (-1,0) The point on the x-axis where it intersects with the y-axis.

coordinate plane

• A plane formed by the intersection of a horizontal number line called the x-axis and a vertical number line called the y-axis

• A flat surface that extends infinitely in all directions

• A three-dimensional space defined by length, width, and height

• A grid system used for mapping geographical locations

y-axis

• The horizontal axis on a coordinate plane

• The vertical axis on a coordinate plane

• The diagonal axis on a coordinate plane

• The axis representing the independent variable

quadrant

• One of four sections into which the coordinate plane is divided

• A type of angle measuring 90 degrees

• A point where two lines intersect

• A method of graphing linear equations

plot

• To place a point on a graph or map

• To create a story outline

• To draw a picture

• To analyze data trends
