  • Rectangular Coordinate System
    A two-dimensional grid formed by intersecting perpendicular number lines, used to plot locations with two values.
  • Cartesian Plane
    A grid with horizontal and vertical axes, allowing representation of points with ordered pairs.
  • X Axis
    The horizontal reference line in a two-dimensional grid, used for plotting the first value in an ordered pair.
  • Y Axis
    The vertical reference line in a two-dimensional grid, used for plotting the second value in an ordered pair.
  • Origin
    The central point where the horizontal and vertical axes intersect, represented by the pair 0, 0.
  • Ordered Pair
    A set of two numbers in parentheses, indicating a specific location on a two-dimensional grid.
  • Quadrant
    One of four regions created by the intersection of the axes, each with distinct sign combinations for values.
  • Two-Dimensional Plane
    A flat surface defined by two perpendicular axes, allowing plotting of points with two values.
  • Linear Equation
    A mathematical statement involving two variables whose graph forms a straight line on a grid.
  • Table
    An organized arrangement of values used to systematically calculate and display pairs for graphing.
  • X-Intercept
    A location where a graph crosses the horizontal axis, with the second value always zero.
  • Y-Intercept
    A location where a graph crosses the vertical axis, with the first value always zero.
  • Solution Set
    A collection of pairs that satisfy a mathematical statement, often visualized as points on a grid.
  • Graph
    A visual representation of mathematical relationships, created by plotting points and connecting them.
  • Number Line
    A one-dimensional reference used for plotting single values, forming the basis for axes in a grid.
