Kristen is feeding her llamas. she uses 5 1/4 cups of a grain and vitamin mixture to feed 7 llamas. which of these equations represents the relationships between x, cups of food mixture, and y, number of llamas?

The point that would not be effected would be (15,0).

The other point are located off of the axis in the coordinate plain and would be flipped when reflected over the x-axis. However, this point, because it is located directly on the x-axis, would not be changed as a result of a reflection across the x-axis. It would reflect onto itself.
