Linear
dose response 
A linear dose
response is a relationship between dose
and biological response that is a straight line. In other
words, the rate of change (slope) in the response is
the same at any dose. A linear dose response is written
mathematically as follows: if Y represents the
expected, or average response and D represents
dose, then
Y = aD
where a is the slope, also called the linear coefficient.

dose, and Linearquadratic
