Find a vector equation and parametric equations for the line. (use the parameter t.) the line through the point (1, 0, 9) and perpendicular to the plane x + 2y + z = 7

r=<1,0,9>+t<1,2,1>

and

x=1+t

y=2t

z=9+t

Step-by-step explanation:

A vector perpendicular to the plane :

is given by (a,b,c)

So a vector perpendicular to given plane will have :

(1,2,1)

..

yo answer should be 6 if im not mistaken

step-by-step explanation:

i believe the correct answer is b.
