Data with two variables
A linear function of the form y=b
a condition that a solution must satisfy
A value that shows how close data points are to a line
the function y=x
generated ordered pairs of the inverse relation
the set of ordered pairs obtained by exchanging the x-coordinates with the y-coordinates of each ordered pair in a relation
The use of a linear equation to the predict values that are outside the range of data.
The use of a linear equation to predict values that are inside of the data range
An algorithm to find a precise like of fit for a set of data
line of fit
A line that describes the trend of the data in a scatter plot
A type of best-line that is calculated using the medians of the coordinates of the data points
Lines in the same plane that do not intersect and either have the same slope or are vertical lines.
Lines that intersect to form a right angle
An equation of the form y-y1=m(x-x1) where m is the slope and (x1,y1) is the given point on a nonvertical line.
a scatter plot shows the relationship between a set of data with two bariables, graphed as ordered pairs on a coordinate plane
An equation of the form u=mx+b where m is the slope and b is the y-intercept.
