What is the scale factor in the following dilation? The smaller triangle is the pre-image.
Two triangles are shown on a grid.The smaller triangle has:
· a vertex two units from the right of the bottom left corner of the grid and one unit up from the bottom of the grid.
· a vertex five units from the right of the bottom left corner of the grid and one unit up from the bottom of the grid.
· a vertex three and one-half units from the right of the bottom left corner of the grid and four units up from the bottom of the grid.
The larger triangle has:
· a vertex four units from the right of the bottom left corner of the grid and two units up from the bottom of the grid.
· a vertex ten units from the right of the bottom left corner of the grid and two units up from the bottom of the grid.
· a vertex seven units from the right of the bottom left corner of the grid and eight units up from the bottom of the grid.

why did you get me a 1/4

I apologize for the oversight in my previous response. The correct scale factor for the dilation provided in your question is indeed 1/3. Thank you for pointing that out.
