B. Reflect PQR across a horizontal line through R, and then translate the image so R aligns with Z.

Step-by-step explanation:

Imagine a horizontal line through point R. Once you reflect the triangle across this line, it will be facing the same direction as triangle XYZ. Then, once you align R with Z (they are corresponding points!) the triangles will be directly on top of each other.

A word for the relation between x and y in the equation y = k x is ___ variation.

nikdorinn [45]

For this case we have to define "y" directly with "x" when there is a constant of proportionality "k", such that:

$y = kx$

This is known as direct variation.

On the other hand, if y varies inversely with x we have to:

$y = \frac {k} {x}$

This is known as inverse variation.

Answer:

$y = kx$ , direct variation
