How do you interpret the slope and y intercept in a real world case?

Positive correlation = the slope of the scattered dots will rise from left to right (positive slope) Negative correlation = the slope of the scattered dots will fall from left to right (negative slope) No correlation = no real visible slope, the dots are too scattered to tell.
The slope of a line on a graph can be zero, or any positive or negative real whole number or fraction or decimal.
Roads are an example of intersecting lines in the real world.
