Question

Find the slope of a line parallel to each of the following lines.

A. y-x=-3

B. 5y+3x=1

C. 2x-5y+10=0

Answer 1

Y=MX+B FORM?

Answer 2

Yup that is the first step

Answer 3

First rearrange the equation into that form

Answer 4

y=x+3

Answer 5

Now, do I subtract 3?

Answer 6

Well we know that the slope of a parallel line will have the same slope as the original line

Answer 7

so all ya gotta do is fine the slope of this line

Answer 8

Now your equation is in the form
y=mx+b
where m=slope

Answer 9

Yeah, I know

Answer 10

So what is m in this equation?

Answer 11

Btw you are wrong the first equation becomes
y=x-3

Answer 12

The m is stil the same in this case. SO in reality it wont change the answer

Answer 13

So what is our m in y=x-3?

Answer 14

x?

Answer 15

Nopeeee
y=mx+b
y=1x-3
So in this case our m=1 and b=-3

Answer 16

oh, so I add 3?

Answer 17

can you show how u got that?

Answer 18

OKKKKKKKK
listen up kid

Answer 19

We moved our equation into the form y=mx+b

Answer 20

ok

Answer 21

so we started off with y-x=-3
and then we converted it into y=x-3

Answer 22

y=1x-3
is in the form y=mx+b

Answer 23

Where our m=1 and b=-3

Answer 24

Okk lemme give you another example
Lets say we have the equation y=3x+5
The equation is in the form y=mx+b
where m=3 and b=5

Answer 25

Do you follow?

Answer 26

Basically the m is the number in front of the x

Answer 27

Yes, I get it and sorry, I was away for a couple minutes...

Answer 28

so m is our slope so for our first equation the slope is 1

Answer 29

ok, question 2 know

Answer 30

ok first put it into y=mx+b form

Answer 31

5y=3x+1

Answer 32

3-3 cross out; 5-3=2

Answer 33

2y=1/2

Answer 34

whatttt what is 3-3 crossout???

Answer 35

subtract 3 from 5 and from 3

Answer 36

We are trying to isolate y
Sooo we have 5y=-3x+1
Now we divide the whole equation by 5 and what do we get?

Answer 37

So, I was wrong?

Answer 38

Yup

Answer 39

oh

Answer 40

I got 3/5

Answer 41

me what?

Answer 42

y-x=-3

Answer 43

i dunno sorry

Answer 44

it's ok

Answer 45

okay
