Question: Question: Alternative vector equation for the following line? (Change both the point and the direction vector:) w = (4, -1, 3) + t(-2, 1, 7)

Question:

Alternative vector equation for the following line? (Change both the point and the direction vector:)

w = (4, -1, 3) + t(-2, 1, 7)

Answer:

Let t = 2

w = (4, -1, 3) + (2)(-2, 1, 7)

= (4, -1, 3) + (-4, 2, 14)

= (0, 1, 17)

An alternative vector equation for the line is:

w = (0, 1, 17) + t(-4, 2, 14)

Please let me know if I have done this correctly.

Thank-you,

Lindsay
