Here we want to find the blue shaded area using the integral.
00:05
So we need to find our bounds here.
00:07
So a is going to be the leftmost point, which here is one, and b is going to be three, because that's the most right point.
00:15
So now we have our bounds.
00:16
What we need to do is find our function.
00:18
So our function is the line here.
00:22
And for this line, we need to find the slope.
00:26
So if we choose two points, which we can go ahead and choose the point right up here, which is at one, four, and then the point at three, two.
00:35
That slope is going to be two to the left and two in the positive up direction, which means our slope m equals negative one...
