Triangle TRY with coordinates T(6, 12), R(-8, 4), and Y(4, -8) is to be reflected across the x-axis.  Which algebraic representation is a reflection across the x-axis?

• (x, y) --> (-x, y)

• (x, y) --> (x, -y)

• (x, y) --> (-x, -y)

• (x, y) --> (-y, x)

• Reflection over the y axis

• Reflection over the x axis

• Reflection over the origin

• Reflection that is 90 degrees clockwise

Determine where Point T' would be if you translated Point T 6 units up and 3 units to the right.

• (5, 1)

• (5, 3)

• (6, 3)

• (3, 6)
