A coworker has been asked to give a report on customer satisfaction with your newly implemented technical support center. She is thinking about using a line chart to trace the increase in customer satisfaction over the last two months, but she would like some advice on how to use graphics appropriately.1. What advice should you give her?a. Begin with a grid divided into squares. b. Arrange the time components vertically on the left-hand side of the chart. c. Avoid plotting the first value when preparing a segmented chart.

how is that middle school

step-by-step explanation:

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'.
