A line of best fit predicts that when x equals 29, y will equal 32.75, but y actually equals 32. What is the residual in this case

The residual is 0.75

Step-by-step explanation:

Recall that the residual is the VERTICAL distance between the y-value of the  data point and the y-value of the predicted line. This distance can be calculated using the absolute value of the difference between these y-values.

Therefore, in our case the residual is: |32 - 32.75| = |-0.75| = 0.75

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'.
