Exploring Adding and Subtracting Rational Expressions

What is a sequence of transformations?

• A transformation that only involves rotation.

• Two or more transformations combined to form a new transformation.

• A transformation that only involves translation.

• A single transformation applied multiple times.

What happens to the y-coordinate when reflecting a point in the x-axis?

• It doubles.

• It is divided by 2.

• It changes sign.

• It remains the same.

If a point (3, -4) is reflected in the x-axis, what are the new coordinates?

• (-3, -4)

• (3, -4)

• (-3, 4)

• (3, 4)

What is the rule for translating a point using the rule X + 9, Y + 2?

• Add 9 to the x-coordinate and add 2 to the y-coordinate.

• Add 9 to the x-coordinate and subtract 2 from the y-coordinate.

• Subtract 9 from the x-coordinate and subtract 2 from the y-coordinate.

• Subtract 9 from the x-coordinate and add 2 to the y-coordinate.

What are the new coordinates of the point (-3, 7) after translating using the rule X + 9, Y + 2?

• (6, -5)

• (6, 5)

• (6, 9)

• (-12, 9)

What is the first step in applying a dilation with a scale factor?

• Translate the points.

• Divide the coordinates by the scale factor.

• Reflect the points in the x-axis.

If a point (12, -4) is dilated by a scale factor of 4, what are the new coordinates?

• (3, -16)

• (12, -1)

• (48, -16)

• (3, -1)

What happens to the x-coordinate when reflecting a point in the y-axis?

• It remains the same.

• It is divided by 2.

• It doubles.

• It changes sign.

If a point (-7, 5) is reflected in the y-axis, what are the new coordinates?

• (7, 5)

• (7, -5)

• (-7, -5)

• (-7, 5)

What is the final step in a sequence of transformations?

• Reflecting in the y-axis.

• Translating the points.

• Reflecting in the x-axis.

• Combining all transformations.
