Define a Function

A set of points with no repeat x-values

100

Given the sequence:

2,5,8,11,...

Whats the Zero term?

-1

100

Describe what the rate of change (or slop is).

It is the change in y over the change in x. 

100

What is the equation for Slope-intercept Form?

y=mx+b

100

If the slope is 3 and the y-intercept is 9, what is the equation?

y=3x+9

200

Describe the Vertical Line test and what it tells us. 

A test we do on a graph. If a vertical line hits the graph twice the graph is not a function. 
200

Given the sequence:

5,1,-3, -7, ...

What is the sequence going up/down by?

- 4

Down 4

200

What is the difference between rate of change and slope?

Rate of change is use when we talk about a situation, slope is just for a given line or equation. 

200

What is the y-intercept and slope of the following equation:

y=-2x-5

y-int: -5

Slope: -2 (down 2 right 1)

200
What is the slope-intercept ("y=") from of the following equation. 


3x-2y=8

y=3/2x-4

300

Does the following set of points represent a function. 

{(2,4),(3,6),(-2,8),(-1,10),(4,-2)}

YES - No repeat x-values
