Graphing
y = −x − 2
y = 2/3 x + 3
(−3, 1)
y = 2x + 7
y = 3x + 9
(−2, 3)
−3x − 2y = 10
2x + 2y = −6
(−4, 1)
What did the calculator say to the student?
You can always count on me.
y = −x + 1
y = 1/4 x − 4
(4, −3)
4x − 6y = −10
−6x + y = −9
(2, 3)
4x + 2y = 10
−8x + 4y = −28
(3, −1)
Why was the math book sad?
Because it had so many problems.
y = x + 4
y = − 5/3 x − 4
(−3, 1)
−6x + y = 4
−6x + 3y = 12
(0, 4)
x − 7y = −27
−10x + 14y = −10

Why did the student bring a ladder to math class?
To reach the high numbers!
14x + 60 = 10y
−40 = 5y + 7x
(−5, −1)
4x − y = 5
−6x + 5y = 17
(3, 7)
−6y + 3x = −12
42 + 24y = 21x

What’s a math teacher’s favorite type of story?
One with a good plot.
0 = −5y − 2x − 15
4x − 5y = −15
(−5, −1)
−4x + 4y = −8
−x − 6y = −23
(5, 3)
14y = 12x − 70
0 = 5y + 30 − 5

Why did the boy eat his math homework?
Because the teacher said it was a piece of cake.
