4. Go to https:/ /www.desmos.com/calculator/u8wt5rwon (This will graph 2D vectors). Graph the vectors v, = (3, 5) and v2 = (-1, 4). a. [6 pts] Find the vector v, + V2 both algebraically and graphically. Algebraically: Sketch a picture (or paste the picture from the grapher) of v, + v2 . b. [6 pts] Find the vector V, -V2 both algebraically and graphically. Algebraically: Sketch a picture (or paste the picture from the grapher) of v, - v2
