Question

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

Answer 1

Answer:

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)

Answer 2

Answer:

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.
