Question | Answer |
---|---|
Absolute Value | The distance the number is from zero on a number line. |
Additive Inverse | The opposite of an integer. The sum of an integer and its additive inverse is zero. |
Coordinate Plane | A plane in which a horizontal number line and a vertical number line intersect at their zero points. Also called a coordinate grid. |
Graph | The process of placing a point on a number line at its proper location. |
Integer | Any number from the set {... , -4, -3, -2, -1, 0, 1, 2, 3, 4, ...} |
Negative Integer | An integer that is less than zero. |
Opposites | Two integers are opposites if they are represented on the number line by points that are the same distance from zero, but on opposite sides of zero. The sum of two opposites is zero. |
Ordered Pair | A pair of numbers used to locate a point in the coordinate plane. An ordered pair is written in the form (x-coordinate, y-coordinate). |
Origin | The point at which the x-axis and the y-axis intersect in a coordinate plane. |
Positive Integer | An integer that is greater than zero. |
Quadrant | One of the four regions into which the two perpendicular number lines of the coordinate plane separate the plane. |
X-Axis | The horizontal number line in a coordinate plane |
X-Coordinate | The first number of an ordered pair. It corresponds to a number on the x-axis. |
Y-Axis | The vertical number line in a coordinate plane. |
Y-Coordinate | The second number of an ordered pair. It corresponds to a number on the y-axis. |
