Eva measures the mass of her pet lizard each month. She wrote this equation to describe her lizard's growth.

y = 0.6x + 4

In the equation, x represents the independent variable and y represents the dependent variable. Which of the following can be the quantities that x and y represent?

A

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

C

B

x = the time in months, and y = the type of lizard

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

x = the type of lizard, and y = the mass in grams

Jay Reid · Answer 1

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.

Mareli · Answer 2

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)
