Transformations Test

Front

What is the rule for reflection across the line y = -2?

Back

The rule for reflection across the line y = -2 is that the y-coordinate of each point is transformed by the formula: y' = -y - 4.

Front

What is the rule for reflection across the line x = -2?

Back

The rule for reflection across the line x = -2 is that the x-coordinate of each point is transformed by the formula: x' = -x - 4.

Front

Given the point A at (-6, -2), where would the image be after the transformation T(-4, 2)?

Back

The image would be at (-10, 0).

Front

What is the image of the point (-2, 5) reflected over the line x = 1?

Back

The image is (4, 5).

Front

What is the image of the point (-5, 3) reflected over the x-axis?

Back

The image is (-5, -3).

Front

Given the point B at (5, 2), where would the image be after the translation (x + 2, y - 7)?

Back

The image would be at (7, -5).

Front

What is the general formula for reflecting a point (x, y) over the x-axis?

Back

The image of the point (x, y) reflected over the x-axis is (x, -y).

Front

What is the general formula for reflecting a point (x, y) over the y-axis?

Back

The image of the point (x, y) reflected over the y-axis is (-x, y).

Front

What is the general formula for translating a point (x, y) by (a, b)?

Back

The image of the point (x, y) translated by (a, b) is (x + a, y + b).

Front

What is the image of the point (3, 4) after a reflection over the line y = 2?

Back

The image is (3, 0).
