In this question, we want to find parametric equations for a line segment going from the point 0 ,1 to the point 3 ,4.
00:15
So recall that parametric equations are when we have x equals something in terms of t and y equals something in terms of t.
00:26
That is, we write both x and y as functions.
00:32
Basically, we write the coordinates as functions of a parameter, which we usually use, for which we usually use the letter t.
00:44
So in this simple example, we need x to go from 0 to 3.
00:49
So for example, we could say 3t and then let t range from 0 to 1.
01:03
That would make x go from 0 to 3, as we need...
