Here's the solution to the transformation problem: First, let's define the individual transformations: R (Reflection on the line y = -x): A point (x, y) is transformed to (-y, -x). S (Rotation about the origin through 180^): A point (x, y) is transformed to (-x, -y). The combined transformation is RoS, which means we apply S first, then R. Part 1: Find the single transformation represented by RoS. Let's apply the transformations to a general point (x, y): 1. Apply S to (x, y): S(x, y) = (-x, -y) 2. Now, apply R to the result (-x, -y). Let x' = -x and y' = -y. Using the rule for R, which is (x', y') (-y', -x'), we get: R(-x, -y) = (-(-y), -(-x)) = (y, x) So, the combined transformation RoS maps a point (x, y) to (y, x). This single transformation is a reflection on the line y = x. The single transformation represented by RoS is Reflection on the line y=x. Part 2: Find the co-ordinates of the vertices of the image of ABC. The vertices of ABC are A(1, 2), B(-4, 3), and C(3, 5). We use the single transformation rule RoS(x, y) = (y, x) to find the image coordinates. For vertex A(1, 2): A' = RoS(1, 2) = (2, 1) For vertex B(-4, 3): B' = RoS(-4, 3) = (3, -4) For vertex C(3, 5): C' = RoS(3, 5) = (5, 3) The coordinates of the image A'B'C' are A'(2, 1), B'(3, -4), C'(5, 3). Part 3: Present ABC and its image on the same graph paper. To present this on graph paper, you would plot the following points and connect them to form the triangles: Original Triangle ABC: A(1, 2) B(-4, 3) C(3, 5) Image Triangle A'B'C': A'(2, 1) B'(3, -4) C'(5, 3) Draw the line y=x on your graph paper. You will observe that A'B'C' is the reflection of ABC across the line y=x.
