2. (a) Change in the plot to your second vector. (b) Can you find a linear combination of u and ở that is equal to z? You can use the slidersfor a and b to experiment. aŭ and bʊ are shown as gray vectors on the same plot. If youcan find one, what is it, written as au+bʊ? If not, can you estimate a linear combinationthat is as close to zas possible? What is it? (Include an image of your findings.) (c) Use row reduction to find your answer algebraically. If there is a linear combination, findit; if not, show that there isn't one. Don't try to find the approximation algebraically.Just show that there is no solution. (Note: if you try to solve using the operator,MATLAB will find it.)
