alright- its not that crazy, just a little unusual to me and I can't quite figure it out.
y= 4 - 2x - x^2
Thanks!

it's not a line but a parabola and its vertex is V (-1;5) with a vertical axis of symmetry

This is not a line. It is a parabola. The slope of the curve can be calculated by taking the derivative.
y = 4 - 2x - x²
Take the derivative.
dy/dx = -2 - 2x
To find the slope at any point, just plug the x value into the derivative above to calculate it.

-2X-2.
Slope is obtained by calculating dY/dX. i.e. dY/dX=0-2-2X=-2X-2
