Challenge Problems
Push your limits with challenges.
Question 1
You have a point (2, 5). First, apply a scaling transformation with a factor of 2, then a translation of (3, -2). What is the resulting point?
💡 Hint: Do the scaling first, then add the translation values to the scaled coordinates.
Question 2
If a point is rotated 90 degrees around the origin, what will the new coordinates be for the point (3, 4)?
💡 Hint: Refer to the 90-degree rotation matrix and apply it to the original point.
