Find a set of parametric equation for the line passing through the points (2,3) and (6,-3).
this is an even number in my book and there are no examples in this section on how to find a parametric equation using two points.
An alternative to the method submitted by earboth follows.
Find the equation of the line. Considering the information given, use the point-slope form of the equation of a line and solve for .
Use as the parameter and let to produce the first parametric equation.
Substitute in the slope-intercept form of the equation of the line to produce the second parametric equation.
In case it isn't clear, and are a set of parametric equation for the line passing through the points (2,3) and (6,-3).
It's as easy as finding the equation of a line y in terms of x and substituting t for x.
