Question

After shifting the origin, coordinates of a point changes from (1,1,1) to (3,-6,4). The new coordinates of origin will be

• A. (2,7,3)
• B. (2,-7,3)
• C. (-2,7,3)
• D. (-2,7,-3)

Answer 1

The correct option is D (-2,7,-3)

Let's assume that new coordinate of the origin is (a,b,c), then
$1-a=3\Rightarrow a=-21-b=-6\Rightarrow b=71-c=4\Rightarrow c=-3$
The new coordinate of origin is (-2,7,-3)
