**Slope-Intercept Form: (to the tune of "Three Blind Mice")**

Slope-intercept form,

Let's all sing along.

Y equals M X plus B.

M is the slope and the intercept's B.

That's what makes it so easy.

It's slope-intercept form.

Let's all sing along.

Y equals M X plus B.

M is the slope and the intercept's B.

That's what makes it so easy.

It's slope-intercept form.

**Point-Slope Formula: (to the tune of "My Favorite Things" from The Sound of Music)**

Y minus Y one equals M time times the quantity

of X minus X one, which means I use parenthesis.

This is point-slope form, it gives me some hope,

If I know just one point and I can find slope.

of X minus X one, which means I use parenthesis.

This is point-slope form, it gives me some hope,

If I know just one point and I can find slope.

**Making a Perpendicular Line: (to the tune of "Zip-A-Dee-Doo**-**Dah")**

Just flip the fraction and change the sign.

That's how I make a perpendicular line.

If I know the slope then everything's fine.

Just flip the fraction and change the sign!

That's how I make a perpendicular line.

If I know the slope then everything's fine.

Just flip the fraction and change the sign!

**Slope Formula: (to the tune "The Farmer in the Dell")**

Y two minus Y one

Over X two minus X one.

That’s the slope formula.

It tells rise over run.

Over X two minus X one.

That’s the slope formula.

It tells rise over run.

**Quadratic Formula: (to the tune of "Pop Goes the Weasel")**

X equals negative B

Plus or minus square root,

Of B squared minus four A C,

All over two A.

Plus or minus square root,

Of B squared minus four A C,

All over two A.
