Answer 3

i dnt know?

Answer 4

go

Answer 5

what's going to be our slope?

Answer 6

der i press it

Answer 7

yep, it worked :)

so what's our slope lol

Answer 8

m=y-1 x2-x?

Answer 9

what's the slope of the given line?

Answer 10

y=3/5 x-1

Answer 11

the slope. what's the slope?

Answer 12

:l the slope is either 3/5 or -1, which is it?

Answer 13

3/5

Answer 14

yes, so if a new line is perpendicular to this one, what's going to be the slope of the new line?

Answer 15

3/5?

Answer 16

no, that would make the new line parallel, not perpendicular. perpendicular lines have negative reciprocal slopes of each other. so our new line would have a slope of...?

Answer 17

-1?

Answer 18

sigh

Answer 19

lol

Answer 20

it would have a slope of -5/3

Answer 21

we basically just flipped the numerator and denominator and made it negative

Answer 22

oh lol

Answer 23

ok. so we have our slope: -5/3 and it goes through point (-9,4). what would our equation be in point-slope form?

Answer 24

x-4/y-+4?

Answer 25

no. point-slope form is y - y1 = m(x - x1)...

Answer 26

y-4=m(x-9)

Answer 27

add 4 y=mx-5

Answer 28

stop. you didn't substitute for m

Answer 29

m = slope. what's our slope?

Answer 30

-5/3

Answer 31

and, it +9, not -9

Answer 32

it's*

Answer 33

ok now wat

Answer 34

y - 4 = -5/3(x + 9)

Answer 35

distribute the -5/3

Answer 36

omg how do i do tht lol

Answer 37

sigh

Answer 38

9/3 = ?

Answer 39

3/1

Answer 40

or just 3 lol

Answer 41

lmao slap myself

Answer 42

and 3(-5) = ?

Answer 43

-15

Answer 44

right, so....

y - 4 = -5/3x - 15

Answer 45

add 4 ?

Answer 46

yes

Answer 47

-11

Answer 48

y = -5/3x - 11

Answer 49

yupp

Answer 50

ahhhh my test is almost over can u give me the answer 4 this pretty please im ur fan already <33
. What is the first step of constructing a perpendicular line from a point not on a given line? (Points : 2)
Without changing the compass, from each intersecting arc on the line, construct two arcs on the side opposite the given point.
Draw a line from the point to the intersecting arcs.
From the point not on the line stretch the compass and mark two arcs on the line.
Use your ruler and draw a straight line from the point through the line.

Answer 52

it's either c or d

Answer 53

thnks 4 everything love stay AWESOME :D

Answer 54

lol you're welcome
