Vector u has its initial point at (21, 12) and its terminal point at (19, -8). Vector v has a direction opposite that of u, whose magnitude is five times the magnitude of v. Which is the correct form of vector v expressed as a linear combination of the unit vectors i and j?

v = -10i + 4j

v = -0.4i − 4j

v = 0.4i + 4j

v = 10i + 100j
