# A triangle has corners at #(-1 ,7 )#, #(3 ,-5 )#, and #(7 ,-3 )#. If the triangle is dilated by a factor of #5 # about point #(-2 ,4 ), how far will its centroid move?

##### 1 Answer

Distance moved by centroid

#### Explanation:

Centroid G(x,y) = (-1+3+7)/3, (7-5-3)/3 = (1, -1/3)#

x Coordinate of new centroid =

y Coordinate of new centroid =
