- Let V be the set of all ordered pairs of real numbers under the following operations of addition and scalar multiplication. Define addition and scalar multiplication on V as follows: (a, b) + (c,d) = (a +c+2, b + d-5) and k(a, b) = (ka, kb) a. There exists a zero vector 0 in V such that for any v in V, 0+v=v+0= v. Which ordered pair in V is the zero vector? b. V is not a vector space. Determine one of the vector space axioms that is not satisfied by V, and demonstrate with a counterexample.

Question
Let V be the set of all ordered pairs of real numbers under the following operations of addition
and scalar multiplication. Define addition and scalar multiplication on V as follows:
(a, b) + (c,d) = (a +c+2, b+d-5) and k(a, b) = (ka, kb)
a. There exists a zero vector 0 in V such that for any v in V, 0 + v = v+0 = v. Which ordered pair in V is the
zero vector?
b. V is not a vector space. Determine one of the vector space axioms that is not satisfied by V, and demonstrate
with a counterexample.
