Question

For the line l passing through the points (1,0,1) and (2,4,7) what is the value of c in the following symmetric equations for l?
I need help I could not solve it

Answer 1

x-1=y/4=z-1\c

Answer 2

wat is meaning of symetric here .. are they parrellel

Answer 3

yes they are

Answer 4

d.r's are <x 2-x1,y2-y1,z2-z1>
i.e., <2-1,4-0,7-1> or < 1,4,6 >
eq. of line is
\[\frac{ x-1 }{ 1 }=\frac{ y-0 }{ 4 }=\frac{ z-1 }{ 6 }\]
