Okay, so this is our equation and this is the predicted money spent and this is the number of hours.
00:11
And the first one talks about for one hour increase, we want to know about the money spent.
00:17
So whenever you see this, one hour increase, usually we're talking about the x variable.
00:28
So when it's saying one hour increase, it's talking about slope.
00:36
Okay? this is talking about slope.
00:41
Now, slope is y over x.
00:45
This guy is my slope.
00:48
So in statistics, we don't use fractions a lot.
00:51
So the 1 .84 is always the y, and then the x is always one.
00:58
That's why it's saying for one hour increase, then the money spent, the predicted amount they spend is going to go up by $1 .84.
01:11
So for each hour, they're going to spend another $0 .84.
01:16
But that one hour increase, because one's always on the bottom for our slope, then that's going to be whatever number's on top, the one by the x, is going to be how much the predicted amount, the y is going to change...
