Question

Find the equation of the plane through (7,9,5) parallel to the plane 3x + 4y + 7z = 0.

Answer 1

your gradient is <3,4,7> which is also your normal

Answer 2

amistre knows her vectors well. :)

Answer 3

3(x-7)+4(y-9)+7(z-5) = 0

Answer 4

lol... at least 2 of them ;)

Answer 5

another form of it is:

3x +4y + 7z - (21+36+35) = 0

Answer 6

amistre is a her? :O

Answer 7

online im whatever they wanna picture me as lol

Answer 8

yeah she is a she

Answer 9

or i projected her as a she. a cute she

Answer 10

LOL. is that the eq?

Answer 11

that is the eq

Answer 12

i look like meg ryan if you squint hard enough ;)

Answer 13

aweesome. haha howd u get 21 and those other numbers

Answer 14

first i killed a chicken, then spread its blood around the bedposts, did an incantation, and oijied the results ...maybe

Answer 15

wow thats some talent!

Answer 16

take your normal/gradient; and apply it to the point they gave you

Answer 17

haha lol aight

Answer 18

x-7 y-...... z - ......

Answer 19

i just exapnded the first equation i gave you; they are equal

Answer 20

sweet

Answer 21

for reference; the normal vector is <a,b,c>; and point P(x,y,z) the plane equation is:

a(x-Px)+b(y-Py)+c(z-Pz)=0

Answer 22

ohh awesome.got it!
