vector r=(5+(6/11)d)vector i + (3+(9/11)d)vector j + (7+(2/11)d)vector k

vector v= _____ vector i + _____ vector j + ____ vector k

Write the coordinates of the point on the line that is 11 units in the positive d-direction away from the fixed point in this problem.

**Steve**, Thursday, January 19, 2012 at 12:16amWhat is the "positive d-direction"? d is not a direction, it is a parameter for r(d).

If d is a parameter, any point involving d is not fixed.

Is the fixed point 5i + 3j + 7k and you want r(11)?

**Grace**, Thursday, January 19, 2012 at 12:31amIs it just ((6/11), (9/11), (2/11)) ?
