The following graph shows a proportional relationship. What is the constant of proportionality between y and x in the graph?

answer: 12   they all have at least 28 days

step-by-step explanation: haha

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024
