Answer:

The transformation rule should be applied to the pre-image. The application of the rule results in the point (8, 12). The transformation rule was applied to the wrong point.

Step-by-step explanation:

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 the error.

Answer:

Instead of moving right 4 times and up 7 times, John moved left 4 times and down 7 times.

Step-by-step explanation:

(x + 4, y + 7) = Right 4, Up 7

NOT

(x - 4, y - 7) = Left 4, Down 7
