Question

The slope of the line whose equation is x - 3y = 1 is

Answer 1

What is your question?

Answer 2

A. -3
B. -1/3
C. 1/3

Answer 3

To find the slope simply solve for y.

Answer 4

Okay solving for y so then 3y=1-x

Answer 5

rearrange to the form y = mx + b
the slope is the value of m

Answer 6

correct so far

Answer 7

yes

Answer 8

get rid of the 3 on the left side.

Answer 9

divide both sides by 3?

Answer 10

yes

Answer 11

3y = x - 1
now divide throught by 3

Answer 12

So the answer should be 1/3 is the slope correct?

Answer 13

yes

Answer 14

Okay :) thank you when i first did it for some reason i kept getting 3 but i know what i did wrong now.

Answer 15

y = (1/3) x - 1/3

Answer 16

Good job, see you around!

Answer 17

One more i just want to make sure i have it down

Answer 18

x+y=6
y=6+x
correct so far?? @czesc

Answer 19

No you need to subtract x from both sides

Answer 20

Oh okay y=6-x now what

Answer 21

x + y = 6
-x -x

y = 6 - x

Answer 22

Do I need to divide still or is it just one since it's only x?

Answer 23

what do you need here - the slope again?

Answer 24

I need to know the slope but I want to make sure I know how to do these problems for my upcoming test.

Answer 25

oh ok

compare what we have with the general form which is y = mx + b

we can write y = 6 - x as y = -x + 6

so comparing:-

y = mx + b
y = -x + 6

Answer 26

so m = what?

Answer 27

Oh okay that makes since okay I get it now.

Answer 28

-x can be written -1x

so m = slope = -1

Answer 29

Alright that makes since thank you so much I really appreciate it
