Okay, so here we're told agent hunt transferred classified files from the cia mainframe into his flash drive.
00:07
The flash drive already had 60 megabytes on it before the transfer, and an additional 4 megabytes were transferred onto it each second.
00:14
We're going to graph the relationship between the size of the files on the drive and time.
00:20
Okay, so in order to do our graph, we're going to need an equation.
00:23
Equation.
00:24
So the easiest way to graph a line is to use the y equals mx plus b equation, which is our slope intercept equation.
00:36
So we're going to say that the total amount on the drive is equal to how many, how much is changing every second? well, it's four megabytes changing every second.
00:51
And then plus the amount that we started with, which would have been the 60.
00:56
So now you can see that the 60 matches up with the y -intercept spot, and the 4 matches up with the slope spot.
01:05
So to start graphing this, we know we can put a point at 60 on the y -axis.
01:15
And then to keep graphing what we're going to do is we're going to take input from the x -axis and put it in for the x in our equation so if i take 10 from the x -axis then y is equal to 4 times 10 plus 60 well 4 times 10 so y equals 40 plus 60 so y is going to equal a hundred so i if i go over 10 10 on the x -axis, i'm going to have a point going up at 100.
01:47
I can do, i can keep going, so i can say 20.
01:50
I'm looking for a pattern here...
