The Least Squares Linear Regression app computes the Least Squares Linear Regression equation and computed (x,y) data points.

The Data Entry Screen for the Linear Regression App has two data entry fields for the x: and y: data points

The app computes the Least Squares Linear Regression equation and computed (x,y) data points.the linear regression equation has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable. The slope of the line is b, and a is the intercept (the value of y when x = 0).

The app has a touch enabled graph. Upon touching the graph a vertical line appears. Move the vertical line to the left or right to display the computed (x,y) data pairs.
