One area that comes to mind immediately is that of driving.
Knowing the slope of a hill allows the correct gear to be selected for ascending or descending a hill - the latter extremely important for long steep hills going down where lots of use of the brakes could lead to brake fade and so engine braking, through the use of a low gear, would help; with an automatic transmission, a "hold gear" option to prevent it going up the gears as the vehicle accelerated (due to gravity) would allow the engine braking to be implemented.
One interesting application is the slope of a road - the larger a slope, the harder it is to go up the road, for example with a car - and the more dangerous it is to go down.One application which you may or may not encounter (depending what you work in - but typically useful for engineers) is that the maximum or minimum of a function usually occurs at places where the slope is equal to zero. This fact is used, precisely, to find where a function has a maximum or minimum value.

what are real life design considerations that would apply to a wind generator
they are no uses
Virtually everywhere; in fact the entire notion of the derivative of a function is based on slope. Both slope and derivative have uses in real life, e.g. your position, speed and acceleration can be calculated using either. Or, you could find the derivative of a logistics curve (a curve that models population growth), etc.

Do you mean how is slope used in real life? Well, to plan road building on mountains. Designing roofs so water runs off. Anything that you must plan to not be flat, but slant, has a slope. But, believe it or not, school is part of real life, so, even thouth you might pretend it is not, when you use it in math class that's pretty real.

DNA has many uses in real life. These uses may include use as evidence in a crime scene for example
The slope-intercept equation y = mx + b is that they mechanically substitute for m and b without understanding their meaning.
