Question

5x + 8y = 4y − 5

Find the equation of the line which passes through the point (11,12) and is perpendicular to the given line. Express your answer in slope-intercept form. Simplify your answer.

Answer 1

do you know what the slope intercept form is?

Answer 2

yes

Answer 3

ok so do you know how to get that equation to slope intercept form?

Answer 4

no

Answer 5

ok so u need to get the y by itself

Answer 6

you mean like this

y =

Answer 7

yes

Answer 8

do you know how you would do that?

Answer 9

no indeed

Answer 10

ok so you do the following:\[5x-5x+8y=4y-5x-5\]\[8y-4y=4y-4y-5x-5\]\[4y=-5x-5\]

Answer 11

I got you to there you need to divide both sides by 4 but first do you get how i got 4y=-5x-5?

Answer 12

not exactly per se

Answer 13

and how do i divide both sides by 4, i'm sorry i wasn't all that good with math

Answer 14

its ok. the first thing i did was subtract 5x from both sides. Then i subtracted 4y from both sides.

Answer 15

do you get that?

Answer 16

yes sort of , i'm just trying to figure out how to divide from both sides in simpler times for me to get it

Answer 17

yes sort of , i'm just trying to figure out how to divide from both sides in simpler times for me to get it

Answer 18

terms i meant

Answer 19

so one side has 4y and we need to get the y by itself right?

Answer 20

yes

Answer 21

ok so you divide 4y by 4 to get y all by itself

Answer 22

but what you do to one side of the equal sign you have to do to the other side

Answer 23

so you take -5x-5 and divide it by 4

Answer 24

okay , is it -5x - 5/4 ?

Answer 25

so the equation now would be y=-1.75x-1.75

Answer 26

-1.75

Answer 27

ok but it wants the perpendicular equation that lines up with (11,12)

Answer 28

i see , how could i get it up to there ?

Answer 29

i think i might be right or wrong , is it y = 4/5x + 16/5 ?

Answer 30

i am trying to figure that out rn. its been a while since i have done these things

Answer 31

i understand , i've been out of school since may as i graduated and all this bring me back so i get what you mean lol

Answer 32

I am a super senior in high school

Answer 33

how did you get that equation?

Answer 34

basically, i looked back and i know that it would have to be y - y1 = m(x - x1) to find the line perpendicular

Answer 35

that is the correct answer but I have no clue how you got it.

Answer 36

thank you , i seen from an example . i'll show you

Answer 37

ok
