y=2x+4 as fraction.
What is 2/1 ?
100
When x = 2, this is the value of y.
What is 3 ?

The ordered pair is (2, 3)
200
These three words are used to describe the set of all outputs of a function.
What is the range, y-value, dependent variable?
200
Function or Not ?
What is FUNCTION ?
200
The answer to f(x) = x + 1 when x = -5.
What is -4 ?
f(x) = x + 1
f(-5) = (-5) + 1 = -3 (substitute -5 for x in the equation and solve)
200
This is the domain of the set
{(2, 5), (-9, 3), (-2, 12), (0, 7), (-9, 4)}
What is {-9, -2, 0, 2}
200
This is the slope of
6x - 3y = 4
What is 2 ?
You must get this in Slope-intercept form first.
-3y = -6x + 4 (Isolate the term with the "y" )
y = 2x - 4/3 (Divide by the coefficient of the "y")
200
This is the y-value, f(x), when x = 0.
What is 4 ?
From the graph, when x=0, y=4 (0, 4)
300
A relation that pairs each x value with only one y value.
What is a Function ?
300
Is this a function ? and Why or why not ?
What is NOT a Function, because x's repeat at 8 ?
300
They functioned as the epitome of musical creativity in this, the world's best rock band.
Who are the Beatles ?
I can't believe you have to ask.
300
This is the domain of the function mapped 
What is {-3,-1,2, 4}
300
This is the y intercept of y = -3x - 5 ?
Give your answer as an ordered pair.
What is (0, -5) ?
300
When x=4, what is y? What is f(4) ?
What is -2 ?
f(4) = -2 When x =4, y=-2
400
This visual test can be used to determine if a graph is a function?.
What is the Vertical Line Test?
400
Function or Not ? Why ?
x y
1 2
2 5
6 2
2 9
5 1
What is Not a Function, because the input (x) of 2 has two different outputs (y)?
400
It's the output of the equation g(x) = 4x - 1,
if x = 2
What is 7 ?
g(x) = 4x - 1
x = 2
g(2) = 4(2) - 1 = 8 - 1 = 7
400
This is the RANGE of the points in the graph.
What is {-6, -5, -2, 3, 5}
400
This is the y-intercept of the equation 5x - 7y = -35, written as an ordered pair.
What is (0, 5) ?
5x - 7y = -35
-7y = -5x -35 (isolate the term with the "y")
y = 5x/7 + 5 (divide all terms by the coefficient)
In the y = mx + b form, b=5
400
This the output when the input is -3.
When x = -3, what is y ?
What is -3 ?
f(-3) = -3 When x = -3, y= -3 (-3, -3)
500
This is an example equation of a vertical line.
What is x = n (any number) ?
500
Function or Not ?
What is Not a function?
Does not pass the Vertical Line Test.
500
It's the output of the equation f(x) = -2x
if x = -18
What is 36 ?
f(x) = -2x
if x -18
f(x) = -2(-18) = 36
500
This is the domain of the graphed points.
What is
D= {-6, -1, 2, 4, 5}
500
This is what we call the slope of x = 2.
What is "undefined" ?
x = 2 describes a vertical line:
whatever the value of y, x is always 2
(2, -3), (2, -1), (2, 0), (2, 2), etc.
The slope of a vertical line is considered "undefined."
500
This is the Slope Intercept form
of the linear equation
2y - 5 = 2x
What is y = x + 5/2 ?
2y - 5 = 2x
2y = 2x + 5 (add 5 to both sides to Isolate the term with the "y" in it)
y = x + 5/2 (divide all terms by 2, the coefficient of the "y" term)
