Asked by Mr bob

ab has endpoints at (2,3) and (2,5). after a dilation with a center at the origin and a scale factor of 15 , what would be the length of the image of ab ?

1/5 units
2/5 units
2 units
10 units
Answered by oobleck
both points are on the vertical line x=2, so they are just 2 units apart
so multiply all coordinates (and thus distances) by 15
I suspect a typo, since the result is not one of the choices.

Well, which one would be the closest? 10?

Yes, 10 units would be the closest choice, although the correct answer should be 30 units.
