EA Unit 1 Vocabulary

TermDefinition
Arithmetic Sequence A sequence in which their successive terms differ by the same number (that is NOT 0), called the common difference. Add the same term each time.
Constant of Proportionality The constant k in direct and inverse variation equations.
Continuous A function with a graph that is an unbroken line.
Discrete A function with a graph made up of unconnected points.
Domain Set of all first coordinates in a relation or function.
Function A relation in which every domain is paired with exactly one range value (every input has exactly one output)
Function Notation If x is the independent variable and y is the dependent variable, then the function notation for y is f(x), which is read “f of x,” where f names the function.
Initial Value Starting value, y-intercept of a graph (b)
Interval Notation A way of writing subsets of the real number line using endpoints, parentheses, and/or brackets.
Linear Function A function that can be written in the form y=mx+b (x is the independent variable and m and b are real numbers). It is graphed as a line.
Parent Function The simplest function with the defining characteristics of the family.
Point Slope Form The equation of a line in the form of y-y1 = m(x = x1) where m is the slope and (x,y) are specific points on the line
Proportional Relationships Relationships between two equal ratios
Range The set of all second coordinates (or y-values) of a function or relation
Rate of Change A ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable.
Slope A measure of the steepness of a line, calculated by dividing the rise by the run of a graph.
Slope-Intercept Form A linear equation written in the form y=mx+b, (m represents slope and b represents the y-intercept).
Standard Form Ax+By=C (A, B, and C are real numbers and A and B are not both 0).
X-Intercept The x-coordinate of the point where a graph intercepts the x-axis
Y-Intercept The y-coordinate of the point where a graph intercepts 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.
