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

Sample response:

The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4,5) into the rule. You get (4,5) (4+4,5+7). Simplify to get (4,5) (8,12). This is the image. Instead the rule was applied to the image. This is the source of error
