Question

The following measurements were taken of a tree. Do the age and height show direct variation? If so, write the equation of variation.

direct variation y = 0.28x

direct variation y = 0.28x + 3.6

direct variation x = 3.6y

no direct variation

Answer 1

if you divide the age by the height the quotient is 3.57 in each case so it is direct variation

C is correct
