John says the transformation rule (x, y) es002-1.jpg (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?

Question

Vocaloid · Answer

the transformation rule (x + 4, y + 7) means you add 4 to the x-coordinate and 7 to the y-coordinate if you want to transform a point

if you compare the pre-image (4,5) to (0,-2) you'll notice that they used the wrong operation instead of addition (compare the numbers and you'll see the error)
