Question

Point W(–4, 7) was translated as follows: W(–4, 7) -> W’(–2, 4). A student wrote the algebraic rule to describe the translation as (x,y) -> (x-3, y + 2) Evaluate the student’s answer.


A.
Incorrect; the student should add 2 to the x-coordinate and subtract 3 from the y-coordinate.
B.
Incorrect; the student should add –4 + –2 to calculate the x-coordinate and add 7 + 4 to calculate the y-coordinate.
C.
Incorrect; the student should add 3 to the x-coordinate and subtract 2 from the y-coordinate.
D.
The student’s answer is correct.
