Quadrilateral wxyz is translated (-5,3). if point w is located at (5,8), where will its image be located?

The translation simply tells you how to operate on the coordinates of the points. So, translating means that you have to subtract 5 to the x coordinate and 3 to the y coordinate.

So, point is mapped onto

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
