If an image of a triangle is congruent to the pre-image, what is the scale factor of the dilation?

The scale factor of the dilation is 1 because the image and pre-image share the SAME everything (lengths, area, etc.). So if you multiply one of the image’s length by any number other than one, the pre-image will change.

Answer:

Graph # 3

Step-by-step explanation:

-2x + 5y > 15               Let x  = 0  solve for y

 -2(0) + 5y = 15             change the > to an =

     5y = 15

      y =3     Point (0, 5) is on the graph

 Graph # 3 is correct because the y-intercept  is 5  

    x          y

    0          3                    -2(0) + 5y = 15;     5y = 15

    5          5                  -2(5) + 5y = 15;    -10 + 5y = 15;  5y = 25; y = 5

    10         7                   -2(10) + 5y = 15; -20 + 5y = 15; 5y = 35; y = 7

   The graph > the line is dotted and you will shade above the line
