Question 1138985: graph triangle ABC. A (2,5) B (-3,3) C (2,1) and it's image triangle A1 B1 C1 after a dilation with scale factor 2 and center (2,3)
it's the triangle A1 B1 C1 and the dilation i am having issues with. Thank you.

With the center of the dilation at (2,3) and A at (2,5), the difference is (0,2). With a dilation factor of 2, that difference becomes (0,4). So A1 is (2,3)+(0,4) = (2,7).
Similarly, the difference between the center and B(-3,3) is (-5,0); with a dilation factor of 2, that difference becomes (-10,0); then B1 is (2,3)+(-10,0) = (-8,3).
And the difference between the center and C(2,1) is (0,-2); with the dilation factor of 2 that becomes (0,-4); and then C1 is (2,3)+(0,-4) = (2,-1).
A graph of ABC and A1B1C1...
