What's Your Function?
Slippery Slope!
Great
"Intercept"ion!
Miscellaneous Fun!
100

Explain what makes something a function.

Each x input goes to one y output.

100
What is the slope of the line with the equation, y = 3x + 2?
What is 3
100
The point on a line that intersects the y-axis.
What is y intercept
100

Vocab: what is another term for slope?

Rate of change

200

Is this a function? Explain. (4, 2) (5, 4) (5, -3) (6, 3)

No, because the input 5 is assigned to two different y values

200
What is the slope and y-intercept of the line y = -3x - 6?
What is -3 and (0, -6)
200
What is the y-intercept of the line whose equation is y = 4x + 2?
What is 2 or (0, 2)
200

Does the graph y = (1/2)x + 4 contain the point (2,5)?

Yes, because 5 = (1/2)2 + 4

5 = 1 + 4

5 = 5

300
Where doe the input and output go on a graph and a table?

GRAPH: input on x-axis, output on y-axis

TABLE: input on the left, output on the right

300

What is the slope of the line y = -4.

The slope is 0

300

Vocab: what is another term for y-intercept?

Starting point, or starting amount, or starting value

300
Is the point (3, -4) a solution to the equation 2y + 3x = -6?
no
400
Describe what the input and output is in this equation: y=7x - 4

input: x

output: y

400

A pool is 40 gallons full and is draining at 1/2 gallon per minute. What would be the slope of this function?

-1/2

400
What is the y-intercept of the line whose equation is y = x?
What is 0
400
Write the equation of the line whose slope is (3/4) and whose X-intercept is -2.
What is y - 0 = 3/4(x - 2) or y = (3/4)x - 3/2
500

If you were given a graph of a circle, would it be a function? Explain.

No, because there would be multiple outputs for one input

500

Find the slope between the points (3, -4) and (4, -5).

What is -1

500
What is the y-intercept of the equation x = -3?
There is not y interept
