Back

y-coordinate

Front

Quadrilateral PQRS is reflected across the x-axis. Which rule describes this transformation?

Back

T(x,y) = (x, -y)

Front

What is the result of dilating a point (3, 4) by a scale factor of 2 centered at the origin?

Back

(6, 8)

Front

∆QRS contains the points: Q(4, 2) R(5, 1) S(3,7). If the triangle is reflected across the y-axis, what will S' be?

Back

S'(-3, 7)

Front

Reflect over x-axis. Which point would be at (3, -6)?

Back

A

Front

What is the effect of reflecting a point (x, y) over the y-axis?

Back

The new coordinates will be (-x, y).

Front

What happens to the coordinates of a point when it is reflected over the x-axis?

Back

The new coordinates will be (x, -y).

Front

Define dilation in geometry.

Back

Dilation is a transformation that alters the size of a figure but not its shape.

Front

What is the scale factor in a dilation?

Back

The scale factor is the ratio of the distance from the center of dilation to a point and the distance from the center to its image.

Front

If a point (2, 3) is dilated by a scale factor of 3, what are the new coordinates?

Back

(6, 9)
