Final answer:
To determine the new vertices coordinates after a translation, add 5 to the x-coordinates and subtract 11 from the y-coordinates of each vertex.
Step-by-step explanation:
To find the coordinates of the vertices after a translation of 5 units right and 11 units down, you must add 5 to the x-coordinate of each vertex and subtract 11 from the y-coordinate of each vertex. Suppose we have a vertex at coordinates (x,y). The new coordinates after the translation would be (x+5, y-11).
An example of this would be if you had a vertex at (2,3). After a translation of 5 units right and 11 units down, the new vertex coordinates would be (2+5, 3-11), which simplifies to (7, -8).
