Question

What is the equation of the line perpendicular to the line y=4/9x-2 that passes through the point (4,3)?

Answer 1

Oh this is easy.

Answer 2

So, the slope of the equation is 4/9

Answer 3

Yes

Answer 4

You simply take the slope and

Answer 5

Ugh, t\

Answer 6

It wont'

Answer 7

my backspace is broken , sorry

Answer 8

Okay, so

Answer 9

You take the slope which is : 4/9

Answer 10

Take the negative reciprocal of it.

Answer 11

Reciprocal means you sflip it.

Answer 12

so if its 4/9 u flip it to 9/4 than make it a negative and it will be : -9/4

Answer 13

so now you have -9/4 which is the slope

Answer 14

now u use the equation y-yz

Answer 15

UGH

Answer 16

So - 9 / 4 x

Answer 17

y-y1=m(x-x1)

Answer 18

you have the cordinates (4,3)

Answer 19

x being 4 and y being 3

Answer 20

so it will look like

Answer 21

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

Answer 22

distribute -9/4

Answer 23

-9/4x and 28/4 and you add three to both sides

Answer 24

which turns out to be

Answer 25

y = -9/4x + 28/4 + 3

Answer 26

28/4 is 7 so

Answer 27

y = -9/4x + 7 + 3

Answer 28

y = -9/4x + 10

Answer 29

get it?

Answer 30

But that isn't an answer choice on here...

Answer 31

let me do it on my paper rq

Answer 32

Okay thank you iv been stuck on this question for awhile.

Answer 33

Ooops/

Answer 34

Okay so -9/4 * -4 is 36/3 which turns out to be 12

Answer 35

I accidentally said 28/4

Answer 36

So we have y = -9/4x + 12 + 3

Answer 37

y = -9/4x + 15

Answer 38

Did you get that?

Answer 39

thank you
