6.51 Extracting values in a list of the form x->value

lst = {{x -> 4, y -> 7}, {x -> 2, y -> 5}, {x -> -1, y -> 10}}
 

one way

({#1[[1,2]], #1[[2,2]]} & ) /@ lst 
 
Out[223]= {{4, 7}, {2, 5}, {-1, 10}}
 

another way

Cases[lst, {_ -> n_, _ -> m_} :> {n, m}] 
 
Out[224]= {{4, 7}, {2, 5}, {-1, 10}}
