Which rule describes the translation PQR --> P'Q'R'?
Ksenya-84 [330]
The "Pre Image" is the image that we started with, so the pink triangle. 
The "Image" is the image that we ended with, so the blue triangle. 

To determine how far we went from the pre image to the image, we can focus on one point, let's say point "P". 

The pre image coordinates for point "P" are 2, 3. 
The image coordinates for point "P'" are -1, 0. 

To get from x value 2 to x value -3, we subtracted 3. 
To get from y value 3 to y value 0, we subtracted 3. 

So, our rule for this translation would be A, (x, y) ----> (x-3, y-3).

What is the slop of a line perpendicular to the line whose equation is 4x+6y=108. Reduce your answer
ahrayia [7]

<u>Answer:</u>

The slope of a line perpendicular to the line whose equation is 4x+6y=108 is \frac{3}{2}

<u>Solution:</u>

Given, line equation is 4x + 6y = 108.

We have to find the slope of the line which is perpendicular to the given line equation.

We know that, <u><em>product of slopes of perpendicular lines equals to – 1</em></u>

So, now, let us find the slope of the given line equation.

\text { Slope of a line }=\frac{-x \text { coefficient }}{y \text { coefficient }}=\frac{-4}{6}=\frac{-2}{3}

Now,

slope of given line \times slope of its perpendicular line = -1

\frac{-2}{3} \times slope of perpendicular line = -1

\text { Slope of perpendicular line }=-1 \times \frac{3}{-2}=\frac{-3}{-2}=\frac{3}{2}

Hence, the slope of the perpendicular line is \frac{3}{2}
