see the x coordinate of the vertical line in changes from x = 2 to x = 6
anonymous
  • anonymous
that should tell you the scale factor

um 3?
anonymous
  • anonymous
nope
anonymous
  • anonymous
it changes to x = 6 but the sharp point shifts left by 2
anonymous
  • anonymous
:/ is it a reduction?
anonymous
  • anonymous
so in total its like from x = 2 to x = 8
anonymous
  • anonymous
I'm confused
anonymous
  • anonymous
shift the dotted figure to the right till the sharp point coincides with the original one
anonymous
  • anonymous
you have to shift by 2. so that means the vertical like is at x = 8
anonymous
  • anonymous
the sharp point??
anonymous
  • anonymous
uh the left sharp point
anonymous
  • anonymous
here are the options for the scale point: scale factor ; reduction scale factor 4; enlargement scale factor 3; enlargement scale factor ; reduction

i know the answer i am just trying to help you get it

|dw:1353133642578:dw| shift the dotted one till point a is the same for the dotted and original one
anonymous
  • anonymous
then check where the line bc is for the dotted and original one
anonymous
  • anonymous
the original line is at x = 2 the dotted one is at x = 8
anonymous
  • anonymous
hmmm so would that be 1/4?
anonymous
  • anonymous
scale factor is 4 yes
anonymous
  • anonymous
and the dotted one is the changed one. it is bigger so...
anonymous
  • anonymous
you should know the answer
anonymous
  • anonymous
4 enlargement?
anonymous
  • anonymous
