TermDefinition
complex fraction a fraction A/B where A or B are fractions and b does not equal zero.
constant of proportionality a constant ratio or unit rate of two variable quantities. It is also called the constant of variation.
constant of variation the constant ratio in a direct variation. It is also called the constant of proportionality.
constant rate of change the rate of change in a linear relationship.
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.
cross products the product of the numerator of one ratio and the denominator of the other ratio. The cross products of any proportion are equal.
dimensional analysis the process of including units of measurement when you compute.
direct variation the relationship between two variable quantities that have a constant ratio.
equivalent ratios two ratios that have the same value.
nonproportional the relationship between two ratios with a rate of ratio that is not constant.
ordered pair a pair of numbers used to locate a point in the coordinate plane An ordered pair is always written in the form/order (x-coordinate, y-coordinate)
origin the point at which the x-axis and the y-axis intersect in a coordinate plane. The origin is at (0,0)
proportion an equation stating that two ratios or rates are equivalent
proportional the relationship between two ratios with a constant rate or ratio
quadrants one of the four regions into which the two perpendicular number lines of the coordinate plane separate the plane.
rate a ratio that compares two quantities with different kinds of units
rate of change a rate that describes how one quantity changes in relation to another. A rate of change is usually expressed as a unit rate.
unit rate a rate that is simplified so that it has a denominator of 1 unit.
unit ratio a unit rate where the denominator is one unit.
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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
