Integers/Coordinate
Plane-Ch. 8-1, 8-6
Question | Answer |
---|---|
Integers | any whole number and it's opposite, including 0{-4, -3, -2, -1, 0, 1, 2, 3, 4} |
Negative Integers | integers less than zero |
Positive Integers | integers greater than zero |
Graphing Integers | put a "dot" on the number line where that integer is |
Opposites | numbers that are the same distance from zero in opposite directions on the number line |
Coordinate Plan | grid used to locate points |
Y-axis | vertical number line |
X-axis | horizontal number line |
Origin | (0,0) |
Negative | numbers below and to the left of zero |
Positive | numbers above and to the right of zero |
Quadrant I | (+,+) (right, up) |
Quadrant II | (-,+) (left, up) |
Quadrant III | (-,-) (left, down) |
Quadrant IV | (+,-) (right, down) |
Ordered Pair | used to located any point on a coordinate plane |
X-Coordinate | ex: (3,4), 3 because it is the first number |
Y-Coordinate | ex: (3,4), 4 because it is the second number |
Direction | ALWAYS-first go right/left, then up/down |
