Purpose

  • Drawing the graph and deriving characteristics based on the given linear formula
  • Composing a linear formula from a corresponding graph

From formula to graph This tool teaches how to draw a graph (a straight line) based on a linear formula. By means of a table, the coordinates of the points of the graph are determined and the graph is drawn.

From graph to formulaThis tool works the other way around. You are presented with a straight line through two points and you learn how to compose the corresponding formula. There are two options:

  • The line goes through a given point on the y-axis and through another point.
  • The line goes through two random points that are not on the y-axis..
