A

x = the time in months, and y = the mass in grams

C

    independent variable - change or control

    dependent - measure

    so ...

    x can be type of lizard (you can change the lizard's size, type/species, etc)

    y can be the mass in grams (u measure mass)

    x = the time in months, and y = the mass in grams

    Step-by-step explanation:

    Since x is dependent to a fixed number, it must be time. This is because 0.6 represents the fixed amount of weight overtime.

    y in the other hand is the result of the process which is the mass of the lizard.
