u=(a,-4) and v=(2,6) are parallel vectors. to find the value of a, I let -4=6k and the find the value of k=-2/3. I multiplied 2, the x component of vector v, with the value of k to get the value of a. 2*-2/3=-4/3. so a=-4/3.

help me find the value of a when u=(a,-4) and v=(2,6) are parallel vectors.
