Practice Questions
Test your understanding with targeted questions
What is the image of point A(3,4) after a translation by vector (2,3)?
💡 Hint: Add the vector components to the original coordinates.
If you reflect point B(1,2) across the y-axis, what is the new location?
💡 Hint: Only the x-coordinate changes sign.

A rectangle has vertices at A(1,1), B(1,4), C(3,4), and D(3,1). Translate it by vector (2, -2) and then reflect it across the line y=2. What are the new coordinates of the rectangle?
💡 Hint: First, perform the translation, then apply the reflection.
An object is dilated by a scale factor of 0.5 from the point (0,0). If the original points are (4,6) and (-2,8), what are the coordinates of the dilated image?
💡 Hint: Multiply both coordinates of each point by the scale factor.
