1.
Translate quadrilateral QRST horizontally 3 units to the left and vertically 4 units up and then reflect the image, Q'R'S'T', in the x-axis. State the coordinates of each vertex of the transformed quadrilateral, Q"R"S"T", after the two transformations have been completed.




2.
Reflect pentagon VWXYZ in the y-axis and then translate the shape horizontally 1 unit to the right and vertically 4 units up. State the coordinates of each vertex of the final transformed image, pentagon V"W"X"Y"Z".

Step 1: Translation

Quadrilateral QRST is horizontally translated 3 units to the left and vertically 4 units up to produce quadrilateral Q'R'S'T'.




Step 2: Reflection

Quadrilateral Q'R'S'T' is reflected in the x-axis to produce quadrilateral Q"R"S"T". Ensure that each key point is the same distance from the x-axis.




The coordinates of quadrilateral Q"R"S"T" are Q"(–8, –7), R"(–5, –8), S"(–4, –7), T"(–6, –5) after the translation and reflection have occurred.
2.
Reflect pentagon VWXYZ in the y-axis and then translate the shape horizontally 1 unit to the right and vertically 4 units up. State the coordinates of each vertex of the final transformed image, pentagon V"W"X"Y"Z".




Step 1: Reflection

Pentagon VWXYZ is reflected in the y-axis to produce pentagon V'W'X'Y'Z'. Ensure that each key point is the same distance from the y-axis.




Step 2: Translation

Pentagon V'W'X'Y'Z' is translated horizontally 1 unit to the right and vertically 4 units up to produce pentagon V"W"X"Y"Z".




The coordinates of pentagon V"W"X"Y"Z" are V"(8, 1), W"(5, 2), X"(2, 1), Y"(3, –1), Z"(7, –1) after the translation and reflection have occurred.
