Question

What is the slope of a line perpendicular to x - 5y = -10?

Answer 1

Write it in the form y=mx+b
where m is the slope :)

Answer 2

Im confused so would u write it 5y=mx-10?

Answer 3

Nope

Answer 4

First subtract x from both sides

Answer 5

so -5y=-10-x?

Answer 6

Right
Now we need this in the form y=mx+c

Answer 7

just rearrange it and you'll get
-5y=-x-10

okay?

Answer 8

okay

Answer 9

Now you don't need that -5 on the left side ,do you?

Answer 10

no

Answer 11

Ok so what do you do?

Answer 12

divide ?

Answer 13

Yes! divide both sides by -5

Answer 14

and be carefull when you divide the right side ,you should divide each term

Answer 15

y=5x+2 ?

Answer 16

Nope

Answer 17

y=(-x/-5)- (10/-5)

Answer 18

so m= 2

Answer 19

Nope

Answer 20

\[y= \frac{-x}{-5}- \frac{10}{-5}\]

Answer 21

-5x+2

Answer 22

\[y= \frac{x}{5}-2\]

Answer 23

\[y= \frac{1}{5}x-2\]

Answer 24

this is of the form y=mx+c
So m is?

Answer 25

-2

Answer 26

\[y= \frac{1}{5}x-2\]\[y=m \ x +c\]
Now tell me what is m ?

Answer 27

just compare both equation

Answer 28

1/5 but thats not one of my anwsers...

Answer 29

0.2?

Answer 30

the anwsers are 2 -3 -4 -5 -2

Answer 31

Sorry for the wrong answer =|

Answer 32

Im confused. idk what to put. i see that we did it right, but i dont understand how the answer doesnt come out to be one of those...

Answer 33

okay.. so for a line of the standard slope intercept form "y=mx+c"
slope is 'm'

and for a line perpendicular to this one, its slope is automatically "-1/m".


so can you rearrange the above line's equation above in the form above, and find 'm'??

post what you get.

Answer 34

huh?

Answer 35

this just confuses me....

Answer 36

OHHH YEH its PERPENDICULAR!!!! OOPS

Answer 37

Its just the same when its perpendicular the equation becomes

\[y=\frac{-1}{m}x+c\]

Answer 38

m=-5 and c= -10?

Answer 39

let me show you S T E P - B Y - S T E P.

V E R Y S L O W L Y!


the line is
x-5y = -10
or, 5y= x + 10

y = x/5 + 2

now comparing (i) with y=mx+c.
coefficient of x = m = slope = 1/5

so slope of the perpendicular line = -1/m = -5



Clear?

Answer 40

some what

Answer 41

go take a break, and come back to this problem with a clear mind. it 'll come to you naturally then :) don't fret
