Answer 11

First what is your y intercept

Answer 12

2?

Answer 13

Correct now what is the slope?

Answer 14

Once you find that than you can put it into the equation y=mx+b

Answer 15

y=1/6+b??

Answer 16

M=slope, the slope I counted wasn't -1/6 but I'll check again

Answer 17

yea ur right sorry

Answer 18

If you go to the closest endpoint how many do you have to go down than to the right?

Answer 19

2 and 6

Answer 20

and 2/6 can be reduced to?

Answer 21

1/3?

Answer 22

Yes now put it into the slope intercept formula

Answer 23

y+1/3+b

Answer 24

What is your b?

Answer 25

And remember it is y=mx+b

Answer 26

idk

Answer 27

Okay sorry I should have explained y=mx+b where m is your slope and b is your y intercept

Answer 28

oh y=1/3+2

Answer 29

Yeah so y=1/3x+2 now we have a coordinate of (b,3) where b is the x value and 3 is the y value so plug in the 3 into the y part

Answer 30

3=1/3+2?

Answer 31

Don't forget your x with 1/3 it's just part of the formula so 3=1/3x+2 now solve for x

Answer 32

how do i do that?

Answer 33

3=1/3x+2 first get rid of the 2 do you know how to do that?

Answer 34

And make sure you bring that 2 to the other side too
