Question

A line segment with endpoints U negative two comma six and V negative five comma negative three is dilated by a factor of 2 with the origin as the center of dilation. Which of the following is a coordinate of the resulting line segment U prime V prime?

Answer 1

V prime negative three comma negative one

V prime negative ten comma negative six

U prime zero comma eight

U prime negative four comma four

Answer 2

U: (-2,6)
V: (-5,-3)

Dilation Factor: 2
Dilation Center: O (0,0)

Can you calculate the distance of U and V from the Origin?

Answer 3

*facepalm*

Answer 4

no @tkhunny look at my answers above urs. those are what i have to chose from....

Answer 5

ok vksmith7, I don't understand your second post. Both of your Vs and Us are prime

Answer 6

oh ok

Answer 7

ya @aegidious

Answer 8

ok, well then since you're dilating from the origin, there's no other annoying adding or subtracting which is good

Answer 9

Simply dilating meaning that your multiplying the distance of the end points from the origin. Since the factor is two, you really just need to multiply the numbers you gave by two.
U (-2,6) turns into U' (-4,12). Do you see? After doing the same with V, you're golden

Answer 10

Once you get your resulting coordinates, line them up with the answers and see which ones fit

Answer 11

i dont get it at all @aegidious

Answer 12

I never look at answers. I recommend you answer my question. We can just prove what the right answer is an in this way, we'll even know if the right answer is not among the given choices.

Answer 13

ok, you know how when your eyes dilate, the black pupil gets really big? That's what you're doing with the coordinates on the graph

Answer 14

yall r to confusing @aegidious @tkhunny
