A goes from (0, 2) to (4, 2)
B from (1, −2) to (2, 1)
C from (−1, 0) to (0, 0)
D from (−3, −5) to (2, −2)
E from (−3, −2) to (−4, −5)
F from (−1, 3) to (−3, 0)
(a) A + B? (b) E − F? (c) −(B + C)? (d) Which two vectors sum to zero?
Ax = 4, Ay = 0
Bx = 1, By = 3 so A+B = 5i+3j
Ex = -1, Ey = -3
Fx = -2, Fy + -3 so E-F = 1i+0j
Bx = 1, By = 3
Cx =-2, Cy = 0
B+C=-1i+3j so -(B+C) = 1i -3j
B and E 1i-3j + -1i+3j
