Translating Triangles on the Coordinate Plane

The triangles on the grid below represent a translation. To form the image, the pre-image moved

• five units right and three units up.

• two units right and three units up.

• five units left and three units down.

• two units left and three units down.

What is the algebraic representation of translating a figure 3 units left and 5 units down?

• (x+5, y-3)

• (x-5, y+3)

• (x-3, y+5)

• (x-3, y-5)

What is the algebraic representation of translating a figure 4 units down?

• (x-4, y-4)

• (x, y-4)

• (x-4, y)

• (x+4, y+4)

When translating a figure on a coordinate plane, which coordinate is affected by movement left and right?

• The x-coordinate

• The y-coordinate

• Neither

What is the algebraic representation that describes this translation?

• ( x , y ) --> ( x + 3 , y + 1 )

• ( x , y ) --> ( x - 3 , y - 1 )

• ( x , y ) --> ( x + 1 , y - 3 )

• ( x , y ) --> ( x - 1 , y + 3 )

What is the algebraic representation that describes this translation?

• ( x , y ) --> ( x + 3 , y + 1 )

• ( x , y ) --> ( x - 1 , y - 3 )

• ( x , y ) --> ( x + 3 , y - 1 )

• ( x , y ) --> ( x - 1 , y + 3 )

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

• (5, 1)

• (2, -5)

• (-1, 1)

• (8, -2)

What is the translation?

• (x - 4, y + 5)

• (x + 5, y - 4)

• (x + 4, y - 5)

Triangle ABC is going to be translated. Where would  A' position be at, if the translation was be (x,y) --> (x+3, y-2)?

• (-1,3)

• (5,3)

• (5,8)

• (3,5)

Which rule would result in a translation of 2 units left and 3 units up?

• (x, y) → (2x, 3y)

• (x, y) → (x - 2, y + 3)

• (x, y) → (-x, -y)

• (x, y) → (x + 2, y - 3)
