Answer:
Q'' : (-1,4), R'' : (-3,1), S'' : (0,0)
Step-by-step explanation:
Given the original vertices of ∆QRS is Q(2,1), R(4,-2), and S(1,-3). Given that these points must undergo a reflection across the y axis, and then a translation along the vector <1,3> means that there are a total of 2 transformations involved.
A reflection across the y axis means that the x value will be negative.
Q(2,1) → Q'(-2,1)
R(4,-2) → R'(-4,-2)
S(1,-3) → S'(-1,-3)
