Performing transformations

The coordinates of triangle JRB are ,J(1, -2) , R(-3, 6) and B(4, 5) . What are the coordinates of its image after the transformation (x, y) ->(x+2, y-1) then reflect over the y-axis?

• J"(3, 1), R"(-1, -7), B"(6, -6)

• J"(3, -3), R"(-1, 5), B"(6, 4)

• J"(-3, -3), R"(1, 5), B"(-6, 4)

• J"(-1, -2), R"(3, 6), B"(-4, 5)

A(-5, -1) L(-3, -2) T(-3, 2)
Rotate triangle ALT 180° clockwise about the origin, then reflect over the line x=1.

• A'' (5, 1) L''(3, 2) T''(3, -2)
• A'' (3, 1) L''(1, 2) T''(1, -2)
• A'' (5, -1)
  L''(3, -2)
  T''(3, 2)
• A'' (-3, 1)
  L''(-1, 2)
  T''(-1,-2)

Identify the sequences of transformations from the green image to the red image to the blue image.

• translation then rotation

• translation then reflection

• rotation then reflection

Choose the correct transformations

• rotate 90 degrees counter-clockwise around the origin, and then reflect over the x-axis

• right 1, down 4, and then reflection over the y-axis

• right 6, and then reflection over the x-axis

• reflection over the line y=x, and then translate up 4, right 2

• reflection over the y-axis, and then (x,y) --> (x-1, y+4)
