In each of the following, the type of variation is given along with 1 data point. Find the variation constant. a. direct variation; y = Kx where x = 3 and y = 6

b. inverse square variation; y = K/x2 where x = –2 and y = 1

c. inverse variation; y = K/x where x = 8 and y = 10

d. inverse variation; y = K/x where x = 3 and y = 3

e. direct square variation; y = Kx2 where x = 5 and y = 15

f. direct variation; y = Kx where x = –7.5 and y = 6.3
