Transformations

A point is translated 3 units left and 4 units up. What is the correct translation rule?

• T(x,y)→(x+3,y+4)
• T(x,y)→(x-3,y-4)
• T(x,y)→(x+3,y-4)
• T(x,y)→(x-3,y+4)

• T(x,y)→(x+1,y-7)
• Horizontally 1 unit and vertically -7 units
• Left 1 Up 7
• T(x,y)→(x+1,y+7)

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

• (5, 1)
• (2, -5)
• (-1, 1)

Determine where X' would be if you translated X 3 units to the left and 9 units down.

• (-4, 4)
• (-10, 2)
• (-4, -5)
• (-1, 5)
