The answer is definitely answer 1,60,-20 divide it by 2 and u get -10,30, its put in different ways with the negative first because your supposed to put ordered pairs in an order of Rise Over Run, so -10 would go first and 30 would go second, the dot thats given might confuse u because its not put in to Rise over run, it should be marked as -20,60 instead its marked as 60,-20.
