Question

John says the transformation rule (x, y) to (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

Answer:

John's error is that he applied the transformation rule to the image instead to the pre-image.The pre-image is the point you start with. To check the transformation rule, substitute the values of the coordinates (4, 5). This results to (4, 5) → (4+4, 5+7). Simplify to get (4, 5) → (8, 12). This is the image.

Answer 2

The transformation of coordinates means the change in the abscissa and ordinate values, you may apply any particular arithmetic operations to transform the coordinates. John used the subtraction operation instead of addition for the transformation of the coordinates.

The transformation rule is given in the question that is the transformation of (x, y) is (x+4, y+7).

John apply the above formula for finding the transformation of (4, 5) and he concluded the answer is (0, -2).

Apply the transformation rule on (4, 5).

Thus,

(4, 5) can be transformed into (4+4, 5+12) that is (8, 12).

Hence, the correct transformation is (8, 12).
