Write a vector equation AND parametric equations of the line through the points A(6,1,5) and B(2,3,6)
direction vector = [8,2,1]
a vector equation
r = (6,1,5) + t(8,2,1)
use that to write the parametrics
how do i write parametrics

since you have
r = (6,1,5) + t(8,2,1), which is correct we can say
x = 6 = 8t
y = 1 + 2t
z = 5  t
