Many statistics courses cover a topic called multiple regression. This provides a means to predict the value of a dependent variable y based on two or more independent variables x1, x2, ..., X The model y = ax, +bx,+c is a linear model that predicts y based on two independent variables x, and x,. While statistical techniques may be used to find the values of a, b, and c based on a large number of data points, we can form a crude model given three data values (x, x2, y). Use the information given to form a system of three equations and three variables to solve for a, b, and c.
