|
|
X coordinate |
The first number on a ordered pair it corresponds to a number on the x axis |
|
|
Coordinate plane |
A plane in witch a horizontal number line and a vertical number line intersect at there zero point |
|
|
Unit rate |
A rate that is simplified so that it has a denominator of one unit |

Origin |
The pint in which the a axis and y axis intersect in a coordinate plane it is at (0,0) |
|
|
Constant rate proportionality |
A constant rate or unit ratio of two variable quantities. It is also called the constant of variation |
|
|
Nonproportional |
The relationship between two ratios with a rate or ratio that is not constant |

Two ratios that have the same value |
|
|
Unit Ratio |
A unit rate where the denominator is one unit |
