Writing about Distance Explain why 1-31 + 191 represents the distance between
the points (-3, -5) and (9,-5).
1

1 - 31 + 191 does not represent the distance of the 2 given points.

The distance between the 2 points is 12

Step-by-step explanation:

Remember distance formula:

When we plug in our values into the distance formula into a calc,

d =

We get d = 12. This does not equal 1 - 31 + 191 (which equals 161).

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
