Bresenham's line algorithm is a line drawing algorithm that determines the points of an n-dimensional raster that should be selected in order to form a close approximation to a straight line between two points.It is commonly used to draw line primitives in a bitmap image (e.g. on a computer screen), as it uses only integer addition, subtraction and bit shifting, all of which are …

Line quality refers to the characteristics of the line drawn. In many cases, line quality refers to the thickness of a line. By varying the line quality (including both thick and thin lines), we create drawings that are more interesting and provide more information to the viewer. Take a look at the line drawing of the apple below.

An equation of this line will appear to the right. A slope and y-intercept can also be entered to change the line of best fit. When you check the box for Show Line of Best Fit, the area least-squares regression line will be displayed. An equation of this …
