Okay, we have this straight line equation naturally and we're told that t goes from 0 to 4, which means the line starts and ends at 0 and 4.
00:13
So let's plug in 0 first.
00:20
So when t is 0, what point do we get? well, if t is 0, i get 3, 6, so call the x, y.
00:34
And then the end point on t equals 4, t is 4, plug in 4 there, 2 times 4 is 8 plus 3 is 11, so x is 11.
00:51
And again, plug in 4 here for t, i get 10, so 11, 10 is the xy coordinate.
01:02
Which means i can now draw this thing, x and y.
01:11
Starts off at 3, 6, start back there.
01:17
There is three, there is six, and it ends up at 1110.
01:25
So we're over here somewhere, there's 11, and there is 10.
01:36
So what it does, it goes from this point here.
01:42
That's my line.
01:44
Starting off here, ending here...
