The new triangle, VWX is an enlargement from your previous triangle, STU.
Point S is (-1, 3) right? and since the triangles are similar, point S is congruent to point V (-2, 6) (angle S is congruent to angle V)
Now, because they are similar, they need the same scale factor or proportion, which in this case is 2 or 2 over 1.
Angle U is congruent to angle X. Point U is (-3, 3) so point X would have to be (-6, 6)
I hope this helps! :)
Sorry if I rambled, haha
