Answer:
Step-by-step explanation:
From the graph attached,
Coordinates of the vertices are,
Q(1, 3), R(3, -3), S(0, -2) and T(-2, 1)
First transformation is to be done,
Reflection of the points across x-axis
,
Rule for the transformation,
(x, y) → (x, -y)
Following this rule,
Q(1, 3) → Q"(1, -3)
R(3, -3) → R"(3, 3)
S(0, -2) → S"(0, 2)
T(-2, 1) → T"(-2, -1)
Further these points have been translated by 1 unit left and 2 units up
,
Rule for the translation given,
(x, y) → (x - 1, y + 2)
Q"(1, -3) → Q'(0, 4)
R"(3, 3) → R'(2, 5)
S"(0, 2) → S'(-1, 4)
T"(-2, -1) → T'(-3, 1)
