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.
