Banalties for the second question i think!
Two planes intersect in a line..I think because planes are not lines
The additive inverse is a number, when added to another number, yields 0.
Its basically the opposite number.....same number, different sign.
so if the number m and 58 are additive inverses, then m = -58 <==
because -58 + 58 = 0
