A line that comes closet to data in the coordinate plane is called the line of best fit.

Step-by-step explanation:

A line of best fit ( also called as a trend line) is a straight line that best represents the data on a scatter plot.

This line may pass through some of the points, none of the points or all of the points.

Hence, A line that comes closest to data in the coordinate plane is called the line of best fit.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
