Quizizz 5.4 Applications of Vectors in Geometry

Find the parametric equation of a straight line passing through the point (3, -1, 2) and is parallel to the vector i+2j-k

Find the vector equation of a line that passes through points A(2, -3, 4) and B(1, 2, 7).

• r = (2i-3j+4k) + t(-2i+j-k)

• r = (3i-2j+k) + t(-i+5j+3k)

• r = (i+2j+7k) + t(2i-3j+4k)

• r = (2i-3j+4k) + t(-i+5j+3k)

• r = (3i-4j+k) + t(2i-j+3k)

• r = (3i-2j+2k) + t(2i-j+3k)

• r = (3i-4j+k) + t(3i-2j+2k)

• r = (3i-2j+k) + t(2i-3j+4k)
