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.
The slope-intercept equation y = mx + b is that they mechanically substitute for m and b without understanding their meaning.
A ladder leaning against a wall. The slated part of the roof of a house.
They are used to mount telescopes and binoculars.
Constructions, drawings, sketches, etc.

Slope is important because it tells the steepness of a rollercoaster or can be used to figure out how high or tall something is!
The slant which lies between the ground and the slope of the Leaning Tower of Pisa.
Proportions are used in real life to determine prices of things.
The slope is any real number.
How do you interpret the slope and y intercept in a real world case?
Believe it or not, school is a real life situation. If you are using it in school it real life for you.
