Whats a Independent/dependent variable and control?

Answer 1

IV is the variable that you manipulate or change the value of

DV is the one the IV has the effect on.

Control is an experimental group that is not manipulated by the IV so that you can tell effects of non-experimental variables.

Answer 2

y = mx + b

y is dependent on x
but of course it depends on your perspective

x = (y-b)/m

then x is dependent on y

a control is probably some type of constraints on the equation such as

y = mx + b where x < 10

Answer 3
