i tried exponentially, and if i put in logy and input y values, then its almost a straight line... how do i find n?

So there's this graph in chemistry with a curved negative slope shape. (x, y) (0.16, 104.61) (0.26, 39.62) (0.35, 21.86) (0.56, 8.54) (0.70, 5.47) (0.98, 2.79) The equation is y=KX^N 1) What is the value of N for which the graph would be a straight line? 2) What is...

ohh, i see it now.. many thanks =]
