If we fit the data as calories as a function of wt loss/week, we need to arrange the data first from lowest to highest wt loss/week lbs and calories. Then, the set of points can be plotted in a graph and a graphical method of line fitting can be used. Curve fitting programs (which are also in the calculator) can be used. The result is:
y = -266.5741x + 2246.5116
The value of R² is 0.7109. The fit is not very good since R² is quite far from 0.99.
By estimating. 5x700 is 3500. i multiplied the first digits in the equation.
