Discuss: Same Line; Different Parametric Equations; Every line can be described by infinitely many different sets of parametric equations, since any point on the line and any vector parallel to the line can be used to construct the equation. But how can we tell whether two sets of parametric equations represent the same line? Consider the following two sets of parametric equations;
Show that the following two lines are not the same by finding a point on Line 
and then showing that is does not lie on Line 
.

and 
in its parametric equations then show that these points also lies on Line 
by finding two values of the parameter that give these points when substituted into the parametric equations for Line
