1

## What is rate of change?

### A ratio that shows how one variable changes with respect to another

2

## How is slope written?

### As a ratio of the vertical change (Rise) to the horizontal (Run) between any two points on a line

3

## Slope is the what for any two points on the same line?

### It is the constant

4

## Slope should be written how?

### As a fraction in simplest form

5

## What is the variable for slope?

### M

6

## What are the four types of slope?

### Positive, Negative, Zero, and Undefined

7

## The main formula for slope on a graph is ...

### M = Rise over Run

8

## The slope formula when given two points is ...

### M = y - y over x - x

9

## What is a linear equation?

### It is a straight line (not a curve), and the x is not squared or cubed.

10

## What are the three forms of a line?

### slope-intercept, point-slope, standard

11

## What is the point slope form?

### y-y = m (x-x)

12

## What is the slope intercept form?

### y=mx+b

13

## What is the standard form?

### Ax+By=C

14

## y-y=m(x-x) what form?

### point slope

15

## y=mx+b what form?

### slope intercept

16

## Ax+By=C What form?

### standard

17

## Why is it called "point-slope" form?

### it has a hidden point and a slope in it

18

## Why is it called "slope-intercept" form?

### it has a slope and an intercept in it

19

## How do you find the hidden point in point slope form? y-y=m(x-x)

### to get your (x,y), take the opposite of the number next to the x to get your x, and take the opposite of the number next to the y to get your y

20

## How do you find the points in Standard Form?

###
(0, __) and ( ,0).

use (0, ) to get the y intercept and (__,0) to get the x intercept.

21

## How do you find the slope in Standard Form?

### m = -A/B (opposite of A over B)

22

## How can you find the y intercept in any form?

### You can always just plug a zero in for x and then solve for y. (0, __).

23

## How can you find the x intercept in any form?

### You can always just plug a zero in for y and then solve for x. (__ ,0)

24

## what do you call something that goes straight up and down?

### VERTICAL

25

## What dod you call something that goes from left to right?

### HORIZONTAL (like looking along the horizon)

26

## What is the name of the point (0,0) ?

### origin

27

## What does VERTICAL mean?

### goes straight up and down

28

## What does HORIZONTAL mean?

### goes from left to right

29

## What is the origin?

### (0,0)
