Question

What equation is perpendicular to y= -x/2-4?

Answer 1

y= 2x-4

Answer 2

use the theory that the product of slope od 2 perpendicluar lines is -1

Answer 3

slope of the given equation is -1/2
lines perpendicular to each other => multiply their slopes we get -1
therefore the slope of the required line is 2
so, the equation is y=2x-4

Answer 4

y=2x-4 is not the correct answer.

Answer 5

the slope of the perpendicular line is always negative reciprocal of the slope of original line.

your given slope is -1/2 it's reciprocal is -2/1 or simply -2 and multiply by negative so it become 2. then substitute to the equation.

y = 2x - 4

Answer 6

y=2x+4

Answer 7

COCOTSOI IS RIGHT WITH THIS ONE

Answer 8

no there is a smal problem in the question itself u have mentioned the line will be perpendicular but not what will be its intercept.Which means that the eqn of any line perpendicular to it is Y=2X+c'(where the value of C' will be determined by any coordinate on the new line )

Answer 9

the correct answer is either y=-4x-1/2, y=-1/2x+4, y=2x+2, or y=1/2x+4 ? Just not sure which of these is correct .

Answer 10

y=2x+2
as it is the only line with slope 2
There are more than one answer if there are no choices given

Answer 11

the + or - doesn't matter at all. it will just move the line horizontally, the meaning of perpendicular is it makes a 90 degree angle when it intersect to the other line that's what we call perpendicular line. ok??

Answer 12

all are perpendicular

Answer 13

What is the slope of a vertical line?

Answer 14

undefined,

Answer 15

1/0
which is undefined

Answer 16

or in some books it is infinite.

Answer 17

KUMAR SAJAN COCO -SIGN brings A VERY BIG CHANGE IN MATHS so its matters everywhere u cant say it doesnt matters and i told u guys cocotsoi method is right and seargent pepper the answer cocotsoi gave above is the right one or else ur question is wrong

Answer 18

kumar sajn 1/0 answer is infinity

Answer 19

The slopes of parallel lines sum to 0, are equal, have negative reciprocals, or sum to 1?

Answer 20

slope of //lines are equal

Answer 21

the only question is what is the perpendicular equation.

it is:

y = 2x + b -----> where b can be any integer.
it can be:
y = 2x + 1
y = 2x + 2
y = 2x + 3
y = 2x + 4
y = 2x + 5

or

y = 2x - 1
y = 2x - 2
y = 2x - 3
y = 2x - 4
y = 2x -5

Answer 22

what is the slope of a line that contains the points, (4,6) & (12,3) ?

Answer 23

(3-6)/(12-4)

-3/8

Answer 24

use the fromula m=y2-y1/x2-x1

Answer 25

Which of the following is the equation of a line parallel to the line y=4x+5?
y=-1/4x
y=-4x+5
y=4x-3
y=5x+4

Answer 26

but that's not one of the answers given, so would it possibly be y=-4x+5?

Answer 27

y=4x-3

Answer 28

@WAHEEDAHMED do you know what are you saying? please don't teach if you are not sure about it.

Answer 29

@kumarsajan thank you so much for your help, could you help me with another problem like this real quick? (:

Answer 30

in parallel lines the slope is always equal.

remember if 2 lines are parallel they will never intersect ( never meet at any point in the graph). as i said before y = mx + b ---> change in b will only move your line in the graph.

if it is still the same as WAHEEDAHMED said then you are drawing a line above the original line which are not parallel.

Answer 31

Which of the following is the equation of a line that is parallel to the line 3x-2y=4?
y=-2/3x-4
y=2/3x+4
y=3/2x
y=-3/2x-2

Answer 32

hey kumar sajan i didnt saw the answer y=4x-3 or i would have told him the same stop acting as the smartest guy in this world i did it by mistake and every post i was also proving him that the slope for the parallel will be the same that is 4 so back off a littlebit smarty pants

Answer 33

@WAHEEDAHMED I"M NOT A GUY !!!!

Answer 34

@WAHEEDAHMED dude read this,

KUMAR SAJAN COCO -SIGN brings A VERY BIG CHANGE IN MATHS so its matters everywhere u cant say it doesnt matters and i told u guys cocotsoi method is right and seargent pepper the answer cocotsoi gave above is the right one or else ur question is wrong

so can you explain me what is wrong in my answer above. :))

Answer 35

i was not to u sergeant

Answer 36

one minute let me have a look at it ....

Answer 37

Can you guys please help me with the problem I posted above @WAHEEDAHMED comment?

Answer 38

first you will change the equation to slope-intercept form ---> y = mx + b

3x-2y=4 --> devide all by -2

(3x - 2y = 4)/-2

-3/2x + y = -2 ----> transpose -3/2x to the other side.

y = 3/2x -2

so what do you think can be the answer. :))

Answer 39

remember the slope of parallel lines are always equal,

y = mx + b ---> where m is the slope. and b is any integer.

Answer 40

What is the standard form equation of the line y=x/5-2?

Answer 41

slope of the given equation is -1/2 lines perpendicular to each other => multiply their slopes we get -1 therefore the slope of the required line is 2 so, the equation is y=2x-4 so what was wrong in this answer isnt it right dude

Answer 42

this answer was given by cocotsoi u can check it i was defending was it wrong

Answer 43

Ohmygosh, y=2x-4 is not the correct answer for the millionth time, alright? Now get over it , my goodness....

Answer 44

we are talking the method not the answer specificaly sergeant

Answer 45

it is correct @sergeantpepper the only thing is that it is not in you multiple options. as i said before the b in y=mx + b doesn't matter if the line is perpendicular or not.

Answer 46

so was i wrong supporting his answer kumar sajan now tell me

Answer 47

i'm out of here. i think you can't find a good answer.

Answer 48

no but you can't say that i'm wrong because my answer is also correct. :))@WAHEEDAHMED

Answer 49

i dont wanna fight or am not saying your wrong or so

Answer 50

i didnt say you are wrong anywhere if i have i am sorry about that
