This Python script is designed to assist in the interactive drawing of lines on an image for the purpose of measuring geometrical properties such as slope and length. Users can manually select points ...

A trend line in a scatter plot represents the general direction of the data. When you're analyzing trends, the slope of this line is a primary indicator of the relationship between the variables.

To plot a linear equation, remember that the slope-intercept form is y = mx + b, where "m" is the slope, or steepness, of the line and "b" is the y-intercept, where it crosses the y-axis, or the ...
