Find the equation of the line joining the points (-7,6,13) and (7,-6,3)

sorry im not getting the correct answer
ohh its ok
i got it right
and also has posted it
wheres it


We know that the equations of the straight lines passing through the points (x1, y1, z1) and (x2, y2, z2) is 

x-x1/x2-x1 = y-y1/y2-y1 = z-z1/z2-z1 

now , the equation of straight lines joining the points (-7,6,-3) & (7,-6,3) is

x+7/14 = y-6/-12 = z+3/6
so , x+7/7 = y-6/-6 = z+3/3
