Question

Find vector equation for the line with the following cartesian equation.

b) x+3y=7

Answer 1

1; 3

Answer 2

r = (1,2) + t(0,1) is the answer..... but why?

Answer 3

r = ( 1,2) + t(1 ; 3) ?

Answer 4

i cant tell

Answer 5

sorry, it's (1,2) + t(3, -1)

Answer 6

yes, let point in line is ( 1; 2) , after let vertices caster : (1; 3 ) => ( 3; -1) or ( -3; 1)

Answer 7

So, how do you do this in steps? W/o knowing the answer?

Answer 8

x=1 , 1 + 3y = 7 => y =2 . have M(1; 2)
coefficient x : 1 ; coefficient y : 3 = > vertices perpendicular ( 1; 3) => vertices parallel ( -3, 1)
==> r = ( 1;2) + t(-3;1)
ok?????

Answer 9

or ==> r = (1, 2) + t(3; -1)

Answer 10

hmm. ok
