Question

find the coordinates of B" after the composition of transformations given by the rule T-2,4° ry-axis. show your work.​​

Answer 1

• B''(8, -3)

Explanation:

Coordinates of point B = (-6, -7)

Transformation applied:

1. Translation T(-2, 4)

• (x, y) → (x - 2, y + 4)
• B(-6, -7) → B'(-6 - 2, -7 + 4) = B'(-8, -3)

2. Reflection over y axis:

• (x, y) → (-x, y)
• B'(-8, -3) → B''(-8*(-1), -3) = B''(8, -3)
