    Look at the given point J(2, 5). Choice A. Now look at point J'(10, 25) What do you do to 2 to end up with 10 and what do you do to 5 to end up with 25?

    Correct. A dilation from the origin must have every new x-coordinate and every new y-coordinate always always be obtained by multiplying the original coordinates by the same number. Since for point J, the multiplier is 5, check the other points of choice A. If every x-coordinate and every y-coordinate was also multiplied by 5, that is the answer. If not, look at the next choice. The multiplier does not have to be 5. It just has to always be the same number.
