Key Takeaways The line of best fit demonstrates the correlation between the different points in a grid. It can be used to find trends by determining the relationship between different points on a graph.For calculation, the following formula is used: Y = C +B¹(x¹) + B²(x²)

The equation of a line of fit is y=mx+b y = m x + b , where m is the slope found in step 2 and b is the y-intercept found in step 3.

A line of best fit can be roughly determined using an eyeball method by drawing a straight line on a scatter plot so that the number of points above the line and below the line is about equal (and the line passes through as many points as possible).

The line of best fit estimates a straight line that minimizes the distance between itself and where observations fall in some data set. The line of best fit is used to show a trend or correlation between the dependent variable and independent variable(s). It can be depicted visually, or as a mathematical expression.
