If you want the differences between consecutive values, you'll quite naturally have one less difference than the actual numbers. You'll just have to leave one of the cells in the table blank.

Select two distinct values of X, designated X1 and X2, from the table, read the corresponding values Y1 and Y2 from the table, and calculate the slope from the formula: slope = (Y2 - Y1)/(X2 - X1)
I would set up a table of values and calculate several of the values of the variables (I would try to calculate the "interesting" values setting one to zero and calculating the other(s), guessing at a maximum or minimum value etc. Then I would plot the values on graph paper.
pretend they = y factor to find x intercepts if they exist, sub 0 for x and find the y-intercept pick a few extra x values, calculate y-values to get a table of values. plot the points from the table. Draw a curve thru the points.
You could calculate it by integrating the chi-square probability distribution function but you are likely to be much better off using a table in a book or on the web.
