Question

John says the transformation rule (x, y) --> (x + 4, y + 7) can be used to describe the slide of the pre-image (4, 5) to the image (0, –2). What was his error?

Answer 1

(x, y) --> (x + 4, y + 7)

means that to transform some point (x,y) add 4 to the x-coordinate and 7 to the y-coordinate

try applying this rule to the pre-image (4,5) and you'll see where the error is
