Using the graph onto the right, we want to estimate the yearly increase in the average global temperature to the nearest hundredth.
00:08
So we want to look at finding a regression line for this.
00:16
So i'm going ahead and i put in my input into the calculator.
00:20
And what i did is i want to say that y is going to be the number, the temperature.
00:27
So that's going to be my first temperature, my first list.
00:30
And my x is going to be the years after 1950, which means i'm not going to use 1950.
00:39
I'm using 0, 10, 20, 30, etc.
00:44
But be careful.
00:44
When you get to the last one, you see that's 2015, so i'm not going in increments of 10 there.
00:50
I change that to an increment of 5.
00:53
So went all the way down and used 65 for my last term...
