How do you translate a shape on a coordinate plane?

Back

To translate a shape on a coordinate plane, you add or subtract values from the x-coordinate and y-coordinate of each point of the shape.

What does it mean to translate a shape 5 units to the right and 2 units down?

Back

It means to move every point of the shape 5 units in the positive x-direction and 2 units in the negative y-direction.

If a point M has coordinates (-3, 5), what are the new coordinates after applying the translation rule (x, y) --> (x - 1, y)?

Back

The new coordinates of M' would be (-4, 5).

What is the translation rule for moving a shape 8 units down and 5 units to the right?

Back

The translation rule would be (x, y) --> (x + 5, y - 8).

How can you describe the transformation (x, y) --> (x + 2, y - 3)?

Back

This transformation can be described as sliding the shape 2 units to the right and 3 units down.

What is the relationship between the original coordinates and the translated coordinates?

Back

The translated coordinates are obtained by applying the translation rule to the original coordinates.

What is the significance of the x-coordinate in translations?

Back

The x-coordinate determines the horizontal position of a point, and changes to it result in left or right translations.
