Question 2 • Pre-Algebra - MA3119 B-CR

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. What did you include in your response? Check all that apply.The transformation rule should be applied to the pre-image.The application of the rule results in the point (8, 12).The transf

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

Explanation

The response says the transformation rule should be applied to the pre-image, which is the starting point. It substitutes (4, 5) into the rule and gets the image (8, 12). It also identifies the error: the rule was applied to the wrong point.
