The formula for a parabola is $y = ax^2 + bx + c$ , where $a, b and c$ are numbers.
If you take the derivative of this:
$d/dx (ax^2 + bx + c) = 2ax + b$
So the derivative function is $y = 2ax+b$
If you grave this, you will always get a line, since this is a function of the first order.

Hope this helped.
