The western beach loses two feet or 10 feet every five years, and the western beach is getting narrower.
What is the line of best fit?
A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
It is given that:
Two ocean beaches are being affected by erosion.
The table represents the width, in feet, of each beach at high tide measured where 1995 is represented by the year 0.
Every year, the western beach loses two feet, or 10 feet every five years. Every year, Dunes Beach gains 5 feet, and every five years, the beach loses 25 feet.
Since the western beach is getting narrower and the dunes are getting wider, no two ocean beaches will ever be the same width.
Thus, the western beach loses two feet or 10 feet every five years, and the western beach is getting narrower.
