Why do all transformation preserve distance

Mathematics
1 answer:
yuradex [85]3 years ago
7 0
Well, a distance-preserving transformation is called a rigid motion, and the name suggests that it <em>moves the points of the plane around in a rigid fashion.</em>

A transformation is distance-preserving if the distance between the images of any two points and the distance between the two original points are equal.

If that's confusing, I get it; basically if you transform something, the points from the transformation are image points. Take the distance from a pair of image points, and take the distance from a pair of original points, and they should be the same for a <em>rigid </em>motion.

I keep emphasizing this b/c not all transformations preserve distance; a dilation can grow or shrink things. But if you didn't go over dilations, don't say nothin XD

Find the x intercept and y intercept for 6x-2y=18 . provide an explanation and show steps
allochka39001 [22]

Answer:

The slope intercept form would be y = 3x - 9

Step-by-step explanation:

To find this slone in slope intercept form, all we need to do is solve for y.

6x - 2y = 18 ---> Subtract 6x from both sides

-2y = -6x + 18 ----> Divide both sides by -2

y = 3x - 9
