Below are sample questions representative of the exercises included on this worksheet and related GEO.74 Graph reflections and identify lines of reflection skill assessments:

Problem 1Difficulty: Mastery
A logo outline has vertices P(-7, -2), Q(-5, 3), R(-1, 4), and S(0, -1). Which image is the reflection across x = -3?
AP'(7, -2), Q'(5, 3), R'(1, 4), S'(0, -1)
BP'(-7, 2), Q'(-5, -3), R'(-1, -4), S'(0, 1)
CP'(-2, -7), Q'(3, -5), R'(4, -1), S'(-1, 0)
DP'(1, -2), Q'(-1, 3), R'(-5, 4), S'(-6, -1)
Solution & Explanation:For reflection across x = -3, use x' = 2(-3) - x = -6 - x and keep y the same. This gives P'(1, -2), Q'(-1, 3), R'(-5, 4), and S'(-6, -1).
Problem 2Difficulty: Mastery
A coordinate diagram shows quadrilateral ABCD and its image A'B'C'D'. A(-5, 1) maps to A'(1, 1), and B(-4, 4) maps to B'(0, 4). Which line is shown as the line of reflection?
Ay = -2
Bx = 1
Cx = -2
Dy = 1
Solution & Explanation:The y-values stay the same, so the mirror line is vertical. The x-values for A and A' average to -2, and the x-values for B and B' also average to -2. The line is x = -2.
Problem 3Difficulty: Mastery
A table is supposed to show points reflected across y = 2. Which correspondence is incorrect?
A(1, -3) -> (1, 7)
B(-4, 5) -> (-4, -1)
C(6, 2) -> (6, 2)
D(0, -6) -> (0, 8)
Solution & Explanation:For reflection across y = 2, the original and image y-values must average to 2. In choice D, (-6 + 8)/2 = 1, not 2; the correct image would have y = 10.
