Origin is shifted to the point (-1,2) to form a new co-ordinate system. What will be the co-ordinate of (3,-5) in the new co-ordinate system.
(4,-7)
If the origin moves to (h,k) the coordinates of (x,y) in the new coordinate system will be (x-h,y-k).The x coordinate is the distance we have to travel in the x-direction to reach the point with sign.Similarly y coordinate.
From (-1,2) to reach (3,-5), we have to travel 4 units in the +ive x-direction and 7 units in the -ve y direction.So the new coordinates will be (4,-7) we can directly calculate it as
(3-(-1),-5,-2) = (4,-7)
