## A Graphical Approach

## If we were to graph on the x,y,z, axis all possible values of p

_{1}, p_{2}, and the RSS of an equation, we would get a bowl-shaped area of space. As the graph shows, the RSS is minimized at the lowest point of the bowl. How do we approach this value?We must solve for a minmized RSS through the process of trial and error, iterating values of p

_{1 }and p_{2}until we discover the lowest possible RSS value.
