How to find the maximum value for each sub-list of a list

Questions
1

I have a list with sub lists like;

list = {{{-2, 1}, {3, 10}, {2, 8}}, {{2, 3}, {1, 9}, {5, 2}}, {{4, 7}, {3, 6}, {1, 5}}}

I need a code that gives me the value of x for which y is maximum
for each one of the sub lists. So I would obtain:

{3, 1, 4}
Thanks for any help

Multiple ways are possible:

Part[MaximalBy[Last] /@ list, All, 1, 1]

Or:

Part[SortBy[Last] /@ list, All, -1, 1]
