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
