Document Summary
What is slope? why is it important: it is a ratio. when someone says slope, forget about the definition. No. this means that the surface is flat, and flat surfaces always have a. Something has changed, the vertical distance has changed, the more we lift the table, the surface becomes steeper and steeper and at some point it becomes completely vertical. So there are two things, the horizontal run and the vertical run. Why do we need to know this: the rate of change of slope helps us make predictions about the future, it helps us make smart investment decisions. This slope can be positive or it be negative, or zero or infinity. What does this mean: enemy relationship: if a says yes, b will say no. So a positive slope always has a best friend relationship, i. e positive relationship.
