Term | Definition |
Absolute value | The distance between a number and zero on the number line. |
Cartesian Coordinate Plane | A plane containing two perpendicular axes (x and y) intersecting at a point called origin (0,0). |
Coordinates | An ordered pair, (x,y) that locates a point in a plane. |
Distance | Amount of separation between 2 points. |
Integers | The set of whole numbers and their opposites {...-3,-2,-1,0,1,2,3...}. |
Magnitude | Greatness in size or amount |
Negative numbers | The set of numbers less than zero |
Opposite number | Two different numbers that have the same absolute value. Example:
4 and -4 are opposite numbers because both have an absolute value of 4. |
Ordered Pair | A pair of numbers, (x,y) , that indicate the position of a point on the
Cartesian coordinate Plane. |
Origin | The point of intersection of the vertical and horizontal axes of a Cartesian coordinate plane. The coordinates of the origin are (0, 0). |
Positive number | The set of numbers greater than zero. |
Quadrant | One of the four regions on a Coordinate plane formed by the intersection of the x-axis and the y-axis. |
Rational number | The set of numbers that can be written in the form a/b where a and b are integers and b is not equal to 0. |
Sign | a symbol that indicates whether a number is positive or negative. Example: in -4, the (-) sign hows this number is read “negative four”. |
x-axis | The horizontal number line on the Cartesian coordinate plane. |
x-coordinate | The first number of in ordered pair; the position of a point relative to the vertical axis |
y-axis | The vertical number line on the Cartesian coordinate plane |
y-coordinate | The second number in an ordered pair; the position of a point relative to the horizontal axis |
