Unit 3.1 Make Up Assignment

Front

What happens to the y-coordinate when you reflect an image over the x-axis?

Back

The y-coordinate becomes opposite.

Front

When you translate a point, what operation do you perform on the x and y coordinates?

Back

You add or subtract a number to x and y.

Front

What is the new coordinate of point A(3, 5) after a 180° rotation about the origin?

Back

A'(-3, -5).

Front

What is the rule for reflecting a point (a, b) over the line y = x?

Back

(a, b) → (b, a).

Front

When translating the point (x-4, y), how does it move?

Back

It moves 4 units left.

Front

What is the effect of a reflection over the y-axis on the point (a, b)?

Back

The new point is (-a, b).

Front

What is the effect of a reflection over the x-axis on the point (a, b)?

Back

The new point is (a, -b).

Front

If you rotate a point (x, y) 90° counterclockwise about the origin, what is the new coordinate?

Back

The new coordinate is (-y, x).

Front

What is the effect of a translation of (x, y) by (3, -2)?

Back

The new point is (x+3, y-2).

Front

What is the rule for rotating a point (a, b) 270° counterclockwise about the origin?

Back

(a, b) → (b, -a).
