Can you help with

Exercise 1. (3) Use the subspace tent to determine if the following sets are subspaces of R3. ll - All vectors of the form 0 where a is a. real number. 0 ll - All vectors of the farm 1 where a is a real number. 1 I1 I All vectors of the form 1: where a, b, r: are real numbers such that b = a + c. C Sb + 2c (b) Let W be the set of all vectors of the form 1: in R3 where b,c are real numbers. Find vectors 1? and {U in R3 c such that H = spnn(i,1.5). Why dude this Shaw that W is a subspace of R3
