Answer:

D) a 360° clockwise rotation about the center of the parallelogram will take the parallelogram PQRS onto itself.

Step-by-step explanation:

The parallelogram PQRS is in quadrant III (3) of the coordinate plane. If the image is reflected over the line x = -5 or y = -5, it would be the mirror image of itself and would move either left (x = -5) or down (y = -5) over the lines. A 180° rotation about the center of the parallelogram would move the object to quadrant I (1). However, a 360° clockwise rotation about the center of the parallelogram would cause the object to make a full circle and take the parallelogram PQRS onto itself.

5.Find the slope of a line perpendicular to

Lemur [1.5K]

Hi there!

When the slopes of two perpendicular lines are multiplied the outcome will be -1.

The slope is the number that is positioned in front of the variable x in the formula. In this case the slope of the given line is -2/5.

Let's call the slope of the perpendicular line m and take into account the given data of the question and my earlier explanation. We then find the following:

$- \frac{2}{5} \times m = - 1$
Divide both sides by - 2/5.

$m = \frac{ - 1}{ - \frac{2}{5} } = 2 \frac{1}{2} = \frac{5}{2}$
The answer is B.

~ Hope this helps you!
