Question

Which shows the image of ΔRST after the rotation (x, y) → (y, –x)? On a coordinate plane, a triangle has points R (negative 2, 1), S (1, 3), T (negative 1, 8). On a coordinate plane, a triangle has points R prime (1, 2), S prime (3, negative 1), T prime (7, 1). On a coordinate plane, a triangle has points R prime (1, negative 2), S prime (3, 1), T prime (7, negative 1). On a coordinate plane, a triangle has points R prime (negative 1, negative 2), S prime (negative 3, 1), T prime (negative 7, negative 1). On a coordinate plane, a triangle has points R prime (2, 1), S prime (negative 1, 3), T prime (1, 7).

Answer 1

Answer:

  On a coordinate plane, a triangle has points R prime (1, 2), S prime (3, negative 1), T prime (7, 1)

Step-step explanation

We assume that the coordinates of the vertices of the given triangle are supposed to be ...

  R(-2, 1), S(1, 3), T(-1, 7)

Then the given transformation (x, y) ⇒ (y, -x) will transform these to ...

  R'(1, 2), S'(3, -1), T'(7, 1) . . . . . (matches the first choice)
