copy deck
- Domain
- set of x-values for the function
- Predicted values
- what you think should happen. Plug into the equation for line of best fit.
- Distance Formula
- √ (x-x)² + (y-y)²
- Range
- set of y-values for the function
- Perimeter
- distance around the outside of a figure; the sum of all sides
- STAT keywords & clues
- linear regression model, line of best fit, charts of data
- Perpendicular lines
- intersect at right angles; for example, the x-axis and the y-axis are perpendicular to each other. Their equations have slopes that are opposite reciprocals.
- Parallel lines
- never intersect; their equations have the same slope but different y-intercepts
- Observed values
- what actually happened. They will show up on the chart or graph
- Midpoint Formula
- (average of the 2 x-coordinates, average of the 2 y-coordinates)
