Write a linear equation given a y-intercept of -7 and slope of 5.
y = 5x - 7
Solve 5x - 4(x - 3) = 17
x = 5

Dad Joke time:
What do baby parabola's drink?
Quadratic Formula!
y = 2x - 7
Start at y-intercept of (0,-7)
Go up 2 and right 1 to the point (1,-5)
Write an exponential function with a y-intercept 3 and a point (-1,9).
y = 3(1/3)x
Solve for x: 3x - 17 < 4x + 2
x > -19
(y3 * 2x3y) / y2
2x3 / y2
Mrs Simmons asks, "How many tablespoons are in a cup?"
16
y = 2(3)x
y-intercept (0,2)
Other points (-1, 2/3), (1,6), (2,18), (3,54)
A camera shop charges $3.99 for an enlargement of a photograph. Enlargements can be delivered for a charge of $1.49 per order. Write an equation that gives the total cost of an order with delivery as a function of the number of enlargements.
y = 1.49x + 3.99
Solve x2 + 4x - 72 = 5
x = 7 and x = -11

Mr Straub asks, "During the famous balcony scene in Romeo and Juliet, Juliet looks out into the night and says, "O Romeo, Romeo! Wherefore art thou Romeo?" What is she actually asking during this line?"
She's asking why Romeo has to be Romeo Montague. Why can't he have any other name that isn't associated with the Montagues (her families rival)? DO NOT ACCEPT she's asking where Romeo is - if they say that, disqualify them immediately.
y > -3x + 4
y-intercept (0,4)
Slope: count down 3 and right 1
Connect the points with a dashed line
Shade above the line
The parks and recreation department in your town offers a season pass for $90. As a season pass holder, you pay $4 per session to use the town’s tennis courts. Without the season pass, you pay $13 per session to use the tennis courts. Write a system of equations.
y = 4x + 90
y = 13x
x2 - 16x = -15
x = 15 and x = 1
2y-2 / yx-2 * y4 * (x-4)2
2x10 / y7
Mrs Simmons asks, "What is a pastry blender?"
a cooking utensil used to mix a hard solid fat (like shortening or lard) into flour in order to make pastries.
Graph. (x-int, l.o.s., vertex, and y-int)
y= -x2 - 2x + 3
Roots: 1 and -3
L.O.S.: -1
Vertex: (-1, 4)
Y-Intercept: 3
Write a standard form quadratic equation from the graphing form y = 2(x-3)2 + 4
y = 2x2 - 12x + 22
Solve 5x2 - 10x - 16 = 4x
x = -0.87 and x = 3.67

Mr Straub asks, "In To Kill a Mockingbird, which character does the mockingbird best symbolize?"
Tom Robinson because he is killed even though he's innocent. Mockingbirds don't do anything but sing so it'd be a sin to kill an innocent bird for no reason.
