**Each statement in Exercise is either true (in all cases) or false (for at least one example). If false, construct a specific example to show that the statement is not always true. Such an example is called a counterexample to the statement. If a statement is true, give a justification. (One specific example cannot explain why a statement is always true. You will have to do more work here than in Exercises 21 and 22. If v1 and v2 are in R4 and v2 is not a scalar multiple of v1, then {v1; v2} is linearly independent**
