Summary

Construction of a line joining two points. You can move this line around and display its equation.

The general equation of a straight line is given in the form y = mx+b where m stands for the gradient (slope).

Goals

• To illustrate the relationship between the equation of a straight line and its graph.
• To show that the slope doesn’t change when the line is moved.

Features

Click and drag the mouse to draw a line.
Click and drag the line around the plane.
