This took a little time to figure out because it's not your typical function table or rule. The rule is y = 1/x. The numbers are reciprocals. To finish the table 5 = .2 and 10 = .1. The solution lies in the fact that .5 and 2 are paired twice. .5 = 1/2 and the reciprocal of 1/2 is 2/1. The reciprocal of 2 is 1/2 or .5.

5- 0.125
10- 0.00390625
each of the y variable you would just divide them by 2
0.5/2= 0.25
