Linear Functions

Extrapolate To estimate values within a known range by assuming that the estimated value follows logically from the known values.
Slope The rate at which an ordinate of a point of a line with a coordinate plane changes with respect to a change in the abscissa.
Y-intercept the point where the graph of a function intersects with the y-axis of the coordinate system.
Regression When the regression line is linear(y=ax+b), the regression constant(a)that represents the rate of change of one variable (y)as a function of changes in the other (x); it is a slope of the regression line.
Linear Function a first-degree polynomial function of one variable.
Interpolate A method of constructing new data points within a range of a discrete set of known data points.
Correlation Coefficient indicates the strength and direction of a linear relationship between two random variables.
Regression Equation The equation representing the relationship between selected values of one variable(x)and observed values of the other(y); it permits the prediction of the most probable values of y.
Residuals A quantity remaining after other things have been subtracted or allowed for.
Best Fit Line A line on a graph showing the general direction that a group of points seem to be heading.
