Question

John says the transformation rule (x, y) Right-arrow (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

old question but will respond so this can be closed

the rule (x + 4, y + 7) means that you take the x,y coordinate and add 4 to the x-coordinate and 7 to the y-coordinate

if you take the pre image (4,5) and apply this rule, you **won't** get John's result of (0,-2). instead, you'll find that John subtracted 4 and 7 instead.
