Q.

In 2D-translation, a point (x, y) can move to the new position (x’, y’) by using the equation

A. X’=x+dx and Y’=y+dx

B. X’=x+dx and Y’=y+dy

C. X’=x+dy and Y’=y+dx

D. X’=x-dx and Y’=y-dy

Discuss

Answer : Option:- B

Explanation :

In 2D-translation, a point (x, y) can move to the new position (x’, y’) by using the equation X’=x+dx and Y’=y+dy. Where dx and dy is distance by which object is moved along X and Y axis respectively.
