Answer 2

link doesn't work, maybe try posting a screenshot?

Answer 4

It appears a little bit past -1?

Answer 5

Wait

Answer 6

Is it -4?

Answer 7

yes

Answer 8

so the y intercept is -4

Answer 9

making b = -4

Answer 10

Ahhh...

Answer 11

can you identify 2 points on this line?

Answer 12

Yes...-1, -1 and -2, 2 I think.

Answer 13

good, make sure you use parenthesis when talking about points

so instead of `-1,-1` say `(-1,-1)`

Answer 14

Then I just plug them in for rise over run formula, correct?

Answer 15

yeah tell me what you get

Answer 16

Ok

Answer 17

-3 I believe

Answer 18

For the slope

Answer 19

yes -3/1 = -3 is your slope

Answer 20

m = -3 is the slope
b = -4 is the y intercept

Answer 21

Ok, thank you so much :)

Answer 22

plug those into y = mx+b

Answer 23

Ok, thanks :)

Answer 24

no problem
