QuestionAnswer
Best-Fit Line The line that most closely approximates the data in a scatter plot
Correlation coefficient A value that shows how close data points are to a line
Inverse relation A relation where the set of ordered pairs are switched, as in the x's with the y's and the y's with the x's
Linear interpolation The use of a linear equation to predict values that are inside of the data range
Median-fit line A type of best-fit line that is calculated using the medians of the coordinates of the data points
Parallel lines Lines in the same plane that do not intersect and either have the same slope or are vertical lines
Point-slope form An equation of the form y-y1=m(x-x1) where m is the slope and (x1,y1,) is a given point on a non-vertical line
Scatter Plot A scatter plot shows the relationship between a set of data with two variables, graphed as ordered pairs on a coordinate plane
Bivariate data Data with two variables
Inverse function Function that undoes the action of another function
Linear extraploration The use of a linear equation to predict values that are outside the range of data
Linear regression An algorithm to find a precise line of fit for a set of data
Line of fit A line that describes the trend of the data in a scatter plot
Perpendicular Lines Lines that intersect to form a right angle, have opposite reciprocal slopes
Rate of Change How a quantity is changing with respect to a change in another quantity
Slope-Intercept Form An equation of the form y=mx+b, where m is the slope and b is the y-intercept

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.
