I know that the inversely proportional formula is y = (k)/(x^n) or kx^-n. But how would we find the formula to this problem? They only gave us one set of coordinates, (4,6) and when we plug in those values for x and y what should we be solving for? Because there would be two unknown values we don't know which is -n and k. Please help me with this problem, thank you.
