The Linear Regression (Lines of Best Fit)
The blue line represents the man competitors and the red line represents the woman competitors.
This is the intersection point. This represents when the man competitors will overall do better at discus in the olympics than woman competitors. Based on the image, this will occur around 2001, so the Olympics where this would take place would be at the 2004 Olympics.
The X coordinate
The X coordinate represents the year. The X is marked by fours, because the Olympics is held every four years.
The Y coordinate
The Y coordinate represents the male or female distances. For both genders, the distances were mostly around 68-69.
