15) Which of the following equation is used in 2D translation to move a point(x,y) to the new point (x’,y’)? a.x’ = x + ty and y’ = y + tx b.x’ = x – tx and y’ = y – ty c.x’ = x + tx and y’ = y + ty d.x’ = x + tx and y’ = y – ty
Answer: (c) x’ = x + tx and y’ = y + ty Explanation: We translate a 2-D point by adding translation distance, tx, and ty, to the original coordinates position (x,y) to move the points to a new position (x’, y’). x’ = x + tx y’ = y + ty.
