Question 1021482: ΔRST has vertices ​R(0​,0​), ​S(6​,3​), and ​T(3−3​).ΔRST after a dilation with center​ (0,0) and scale factor one third. What are the coordinates of point Upper T'?

T(3,-3​):
Use the formula for dilation.
1) multiply both coordinates by scale factor: (3%2A%281%2F3%29 ,-3%2A%281%2F3%29)
2) Simplify: (1,-1)
so, the coordinates of point Upper T' are (1,-1)
