This math image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}. It is recommended to name the SVG file “Slope of a line.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
Shows the definition of the (numerical) slope of a straight line in a 2D coordinate system, along with two points and a perpendicular line with its own -1/a slope
Drawn using the "Autoshape" features in MS Word '97, then converted to PNG in a graphics tool.
