Edit Article

When you are learning about linear equations, you must learn several forms of equations. Non-linear topics which are not covered in this article are all kinds of graphs and data that are not reducible into simple line form. The information below is pretty much of an overview (like a menu) under construction. The x1, x2, etc. will be using subscript.

Steps

  1. Convert Miles to Kilometers by a Math Trick (Fibonacci) Step 4.jpg
    1
    See what was given to you that you need first -- to find the equation of a line. You will need one or the other of these two things to use:
    • you have received either two points -- or one point and the slope;
    • you have to find either two points -- or one point and the slope.

    Find the slope from the two given points, if to begin you were given two points, then your first step in any of the methods for writing the equation of the line is to .

Tips

  • In the standard form Ax + By = C the slope is -A/B
  • Create a Line Design showing interesting artistic effects that involve lines or linear equations.

Warnings

  • With any two points on a line, either point may be considered (x1, y1) and either point can be (x2, y2)
