Point j(8,5) was translated as follows: j(8,5) ► j'(2,9). a student wrote the algebraic rule to describe the translation
as (x, y) → (x+6y+4). evaluate the student's answer.
a. incorrect; the student should add 8 + 2 to calculate the x-coordinate and should add 5 + 9 to
calculate the y-coordinate.
b. incorrect; the student added 4 to the y-coordinate instead of subtracting 4 from the y-coordinate.
c. incorrect; the student added 6 to the x-coordinate instead of subtracting 6 from the x-coordinate.
d. the student's answer is correct.
