Terms in this set (...)

bivariate data
Data with two variables
constant function
A linear function of the form y=b.
identity function
The function y=x.
inverse function
A function that can generate ordered pairs of an inverse relation.
inverse relation
A set of ordered pairs obtained by exchanging the x-coordinates with the y-coordinates of each ordered pair in the relation.
linear extrapolation
The use of a linear equation to predict values that are outside the range of data.
linear interpolation
The use of a linear equation to predict values that are inside the data range.
line of fit
A line that describes the trend of the data in a scatter plot.
parallel lines
Lines in the same plane that do not intersect and either have the same slope or are vertical lines.
perpendicular lines
Lines that intersect to form a right angle.
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 nonvertical 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.
slope-intercept form
An equation of the form y=mx+b, where m is the slope and b is the y-intercept.
