How would I go about this?

(1 point) FOR EACH PROBLEM ON THIS ASSIGNMENT, ENSURE THAT YOU TAKE NOTE OF HOW MANY ATTEMPTS ARE GIVEN. SOME OF THE PROBLEMS ONLY ALLOW FOR ONE ATTEMPT DUE TO THE NATURE OF THE PROBLEM. a Determine if the subset of R2 consisting of vectors of the form [ ] , where a. + b = 1 is a subspace. Select true or false for each statement. I 1. The set contains the zero vector v 2. This set is closed under scalar multiplications v 3. This set is closed under vector addition v 4. This set is a subspace
