Line fitting is the process of constructing a straight line that has the best fit to a series of data points. Several methods exist, considering: Vertical distance: Simple linear regression.

Let's just draw a horizontal line at y equals 1.5 over to our graph. And thenMoreSo when y equals 1.5. Let's just draw a horizontal line at y equals 1.5 over to our graph. And then going down we can see that that's going to hear the x-axis at about 1.7.

A line of best fit is a straight line drawn through the maximum number of points on a scatter plot balancing about an equal number of points above and below the line.

The line of best fit can also tell us about the correlation between two variables. For example, we can tell if the variables x and y have: Positive correlation (as x increases, y also increases). Negative correlation (as x increases, y decreases).

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 equation of a line of best fit can be represented as y=mx+b y = m x + b , where m is the slope and b is the y-intercept. We will take a look at two examples show a scatter plot with a line of best fit to understand the concept of how to approximate the equation of a line of best fit and make predictions.

A line of best fit is a straight line that minimizes the distance between it and some data. The line of best fit is used to express a relationship in a scatter plot of different data points.

When drawing the line of best fit, use a transparent ruler to see how the line fits between all the points before you draw it.
