decrease in attendence over the school year: line graph

number of dogs of ten students: stem and leaf

organize hights of 80 adults: bar graph

number of students in three different sports: line plot

Step-by-step explanation:

line graph: used to show increase and decrease patterns

bar graph: used to organize different data without pattern

stem and leaf: used to record different numbers without organization

line plot: used to record amounts for different variation of things

to record the number of dogs ten students-line plot

to show the decrease in attendance over the school year-line graph

to organize the list of heights of a group of eighty adults-stem and left plot

to show the number of students who participate in three different sports- bar graph

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'.
