When a dependent variable increases when the independent variable increases, the rate of change is?

positive
negative
zero
undefined

Well considering the problem says that the dependent variable "increases", the rate of change would be positive.

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
