Kelby is buying beans, rice, and meat at the grocery store. b is the price of the beans, r is the price of the rice, and m is the price of the meat.
match the expressions to their meanings. each meaning may match more than one expression.
for reference:
beans come from a plant and are rich in protein.
rice comes from a plant and is rich in carbohydrates.
meat comes from an animal and is rich in protein.

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'.
