### Rational Explorations: Numbers and their Opposites

TermDefinition
Absolute Value The distance between a number and zero on the number line. The symbol for absolute value is shown in the equation |−8| = 8.
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 The amount of separation between 2 points.
Inequality Any mathematical sentence that contains the symbols: > (greater than), < (less than), (less than or equal to), or (greater than or equal to).
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 with a value less than zero.
Opposite Numbers Two different numbers that have the same absolute value. Example: 4 and −4 are opposite numbers because both have an absolute value of 4. They are the same distance from zero, in opposite directions.
Ordered Pair A pair of numbers,(𝑥, 𝑦), that indicate the position of a point on the Cartesian coordinate Plane.
Origin he point of intersection of the vertical and horizontal axes of a Cartesian coordinate plane. The coordinates of the origin are (0, 0).
Polygon A closed figure formed by three or more line segments.
Positive Numbers The set of numbers whose value is 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 ab where a and b are integers and 𝑏 ≠ 0.
Sign A symbol that indicates whether a number is positive or negative. Example: in −4, the (−) sign shows this number is read “negative four”.
x-axis The horizontal number line on the Cartesian coordinate plane.
x-coordinate The first number in an 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.
