Answer:
From the given graph:
the coordinates of triangle RST are;
R= (2, 1),
S= (2,-2),
T= (-1,-2)
Given: Scale factor = and center of dilation at (2,2)
The mapping rule for the dilation applied to the triangle as shown below:
; where k represents the scale factor i.e, or we can write it as ;
For R=(2, 1)
The image R' =
⇒ R'=
Similarly for S= (2, -2) and T= (-1,-2)
therefore, the image of S'=
⇒ S'=
The image of T' =
⇒T' =
Now, labelling the image of triangle R'S'T' as shown in the figure given below
2x 2 , is the answer the other sneers are incorrect.
60x + 20y is the correct answer
