Equations of a straight line
In this unit we find the equation of a straight line, when we are given some
information about the line. The information could be the value of its gradient,
together with the co-ordinates of a point on the line. Alternatively, the
information might be the co-ordinates of two different points on the line.
There are several different ways of expressing the final equation, and some
are more general than others. (Mathtutor Video Tutorials)

Properties of straight line segments
In this unit we use a system of co-ordinates to find various properties
of the straight line between two points. We find the distance between the two
points and the mid-point of the line joining the two points.

The gradient of a straight line segment
In this unit we find the gradient of a straight line segment, and the
relationships between the gradients of parallel lines and of perpendicular
lines.
