Question

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. A shaded polygon A B C D is graphed in an x y plane, where x axis ranges from 0 to 7 in increments of 1 and y axis ranges from 0 to 6 in increments of 1. The vertices are as follows: A (1, 1), B (2, 3), C (5, 4), and D (4, 2). Polygon ABCD, shown in the figure, is dilated by a scale factor of 8 with the origin as the center of dilation, resulting in the image A′B′C′D′. The slope of C'D' is___ .

Answer 1

The slope of C'D' is equal to the slope of CD because dilation preserves shape which is 2

What is transformation?

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Rigid transformation is a transformation that preserves the shape and size of a figure such as translation, reflection and rotation. Dilation preserves only the shape.

Polygon ABCD has vertex at A(1, 1), B(2, 3), C(5, 4), and D(4, 2).

Slope of CD = (2 - 4) / (4 - 5) = 2

Polygon ABCD is dilated by a scale factor of 8 with the origin resulting in the image A′B′C′D′.

Slope of C'D' = slope of CD (because preserves shape) = 2

The slope of C'D' is equal to the slope of CD because dilation preserves shape which is 2
