Do you know what mathematicians do after it snows?
They make snow angles
y = −x + 1
y = 1/4 x − 4
(4,-3)
4x − 6y = −10
−6x + y = −9
y=3
x=2
4x + 2y = 10
−8x + 4y = −28

Which tool is best for math?
Multi-pliers
y = x + 4
y = − 5/3 x − 4
(-3,1)
−6x + y = 4
−6x + 3y = 12
(0,4)
x − 7y = −27
−10x + 14y = −10

Hey, have you ever noticed what’s odd?
every other number
14x + 60 = 10y
−40 = 5y + 7x
(-5,-1)
4x − y = 5
−6x + 5y = 17
