Question

Write an equation in :
vector form, parametric form, and symmetric form

given (1,2,3) (-3,2,1)

Answer 1

you mean line equation?

Answer 2

yes given the points (1,2,3) (-3,2,1)

Answer 3

ooh that is an easy one

Answer 4

r=r_0+t*v

all except t are vectors

Answer 5

for symmetric form solve for t and cancel it out.

Answer 6

symmetric form

Answer 7

how'd you attach that ?

Answer 8

vector form:
(x,y,z)=(1,2,3) +t(-4,0,-2)
parametric form:
(x,y,z) = (1-4t,2,3-2t)
Symetric:
(x-1)/-4=y-2=(z-3)/-2

Answer 9

there is an attach file button

Answer 10

okay thank you both !
