We need to find the area of a section on a graph that's being enclosed by three different lines and then the x -axis.
00:13
So the first graph that we know is y equals 2x.
00:22
I'll do this one in red.
00:23
We start at 0 ,0, and then we know it goes up 2 over 1 for our slope.
00:28
So i'll just make some points to help kind of get this prepared for us.
00:37
That's plenty.
00:39
And then we'll just draw in our line and do our best to keep it straight.
00:50
And then we have two vertical lines.
00:54
One of them is x equals four.
00:58
And i'll do that one in green.
01:02
X equals four.
01:03
So one, two, three, four right here.
01:07
And it's literally a line that's just straight up vertically.
01:15
The point where it runs into y equals negative 2 is very important.
01:22
We'll keep just that amount there.
01:24
And then the last one is x equals 5.
01:30
Here's x equals 5.
01:31
I believe one spot over...
