Linear Rap Song
Verse One:
To all the students that start to whine because they hate to graph a line
Allow me to help and begin with a slope and give you some hope
Slope is (m) and is the start of the equation
The flow of the graph, does it go up, does it go down
If you can figure it out, you’ll feel relaxed and go to town
Mad question askin’, line blastin’, axis passin’
But you just can quit
Because all of these slopes have more to deal wit
Fractions, that’s how ya see slope a lot
Rise over run, the line on the plot
Now check it, take the change in (y) over the change in (x)
Believe me students; two ordered pairs will get you there
No need to be worried, there’s not much more to know
If a line climbs up, the slope is positive
When the line drops down, then it’s negative
Look at the sign in front of the slope, you know which way the line go
Chorus:
I love it when I see a straight line drawn
To find a line’s true slope, use rise over run
I love it when I see a straight line drawn
Let (x) equal zero, y-intercept’s done
I love it when I see a straight line drawn
(M) equals the slope of the line, and you’re doing just fine
Now y = mx + b. Say it with me, it’s so easy, easy
Verse Two:
How you draw a straight line?
With precision and finesse
I use the formula that is the best
y = mx + b and it’s time to see
Just what that (b) seems to mean
On any graph we have two axis
(x) goes left to right, (y) vertically
(b) is the point where a line crosses (y)
Let’s take an equation and give it a try
y = x + 2, so what you got?
Count 1, 2 up the (y) & make a dot
Use rise over run, up 1 over 1
Draw a line, connect the dots, now you’re done
