Function or Not (table/map)
slope & y-intercepts
Function or Not (x,y) & graph
100

Function or Not 

No, -7 gives two different outputs

100

What is the y-intercept of the function:

y = 2/3x - 10

-10

100

Is it a function? {(2, 3), (4, 5), ( -2, 6)}

Yes, because it does not repeat

200

Function on not?

X is not repeating, automatically YES

200

What is the slope of the function?

y = 3x - 10

3

200

No, it doesn't pass the vertical line test.

300

Function or not?

Yes, different inputs can have the same output (Costco water vending machine)

300

What is the y-intercept of the function?

y = 9x + 4/5

4/5

300

Is it a function? 

{(2, 1), (3, 1), (4,1), (-1,1)}

Yes, the x-values are assigned one y-value

400

Function or Not?

Yes, x is NOT repeating.

400

What is the slope of the function?

y = -5/3x + 10

-5/3

400

Function or Not

No, it does not pass the Vertical line test

500


 x   y

2    4

-3   4

7     7

X is not repeating, automatically YES!

500

Challenge: Rearrange the equation to be in the format y=mx+b to find the slope of the function..

2x + y = 10

-2

500

Do these ordered pairs represent a function?

{ (2,2) , (3,3) , (4,4) , (2,2) , (5,5) , (6,6) }

Yes, each input has exactly one output.
