1

## What is a linear equation?

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

2

## What are the three forms of a line?

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

3

## What is the point slope form?

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

4

## WHat is the slope intercept form?

### y=mx+b

5

## What is the standard form?

### Ax+By=C

6

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

### point slope

7

## y=mx+b what form?

### slope intercept

8

## Ax+By=C What form?

### standard

9

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

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

10

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

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

11

## 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

12

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

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

13

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

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

14

## What is a trick to identify the correct form?

###
Look at the equal sign. What is to the left?

just a y ? then slope intercept

a y + or - something? then point slope

an X and a Y? then standard

15

## 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, __).

16

## 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)

17

## What is a way to remember how to plot points like (-2,4) or (7, 8)

### WALK x then CLIMB y

18

## What are the slopes of the diagonals of a square?

### +1 and -1

19

## A slope of 2/3 is (steeper/less steep) than one.

### less steep

20

## A slope of -5/2 is (steeper/less steep) than negative one.

### steeper

21

## A slope of 1/10 is closer to (zero or one)

### zero

22

## A slope of 7/8 is closer to (zero or one)

### one

23

## A slope of 0.0001 is closer to (zero or one)

### zero

24

## A slope of 5 is closer to (one or undefined)

### undefined (straight up and down)

25

## If a line has a y intercept of 9, then the point _____ is on the line.

### (0,9)

26

## If a line has an x intercept of 9, then the point _____ is on the line.

### (9,0)

27

## If you are given two points, the equation for the slope of the line is

### m = y-y / x-x

28

## People think of the slope as _____ over _____

### RISE, RUN

29

## what form? y = 4x - 3

### slope intercept
