The point (2,3) is first reflected in the straight line y=x and then translated through a distance of 2 units along the positive direction X -axis. The coordinates of the transformed point are
Options
- A(5,4)
- B(2,3)
- C(5,2)
- D(4,5)
Correct answer
C. (5,2)
Step-by-step solution
Let P(2,3) be the given point and Q be the reflection of point P(2,3) about the line y=x . Then, the coordinates of Q are (3,2) Now, the point Q is translated through a distance of 2 units along the positive direction of X -axis. Let the new position of Q be R . Then, the coordinates of R are aligned & R=(3+2,2) & R=(5,2) aligned
