[Hook x2]
Rise up, run out, we're mappin' graphs to the RRR sound
We're talkin' points and slopes, axes and origins
Y-intercepts, and quadrants, all four of them
[Verse I]
The four quadrants start from the top right
Counter-clockwise from the positive x and y
You go around, hit the II and then III
Bottom left, negative, remember that please
Now if you've got a single point on the x-y grid
There's a single pair of values telling you where it is
The x coordinate goes side to side
The y follows the comma to define the point's height
A straight line between two points is a relation
You can represent it with a linear equation
Y = m times x + b
If you wanna know the variables listen to me
M is the slope, that's rise over run
It tells you how steep the line is gonna become
B is the intercept, that's how you a**ess
The point at which the line goes through the y-axis

[Verse II]
Let's say you've got a job and you're earning your pay
You start with 50 bucks and get 9 every day
If you wanna know over a year how much you'll get
Calculating that graph might be your best bet
On the x, you're measuring one day at a time
And your money gets tracked on the vertical y
Now you got some, and you haven't even worked yet
50 bucks, put it up, that's your y-intercept
After day one you got 59
Now you got two points, you can start drawing a line
The slope of that line, remember rise over run
It's dollars over days and you got 9∕1
Remember b, I think that's where we started at
50 dollars up on your graph, the y-intercept
And you know y = mx + b
So now you got y = 9x + 50
