Answer 11

can you explain how you got that please?

Answer 12

i am sorry i haven't taken math in soo long
since i was in highs school

Answer 13

there were two dots, I looked at x and y value of each dot

Answer 14

oh, ok i see what u are talking about now

Answer 15

find slope between two points
slope= y2 - y1
-------
x2-x1

(10,80) (14,120)

slope= 120 - 80
-------
14-10

40/4=10
so 10 calories per minutes

Answer 16

where the one coming from. are we replacing the one?

Answer 17

10 was not the right answer, it says its wrong

Answer 25

yeah,let me relook at the graph

Answer 26

i am looking at it too

Answer 27

I think it might be (15,120) instead of (14,120)
find slope between two points
slope= y2 - y1
-------
x2-x1

(10,80) (15,120)

slope= 120 - 80
-------
15-10

40/5=8
so 8 calories per minutes

Answer 28

that was right

Answer 29

thank you

Answer 30

gotta get my eyes checked out

Answer 31

yea me too lol

Answer 32

how can i identify the y-intercept

Answer 33

it is y value when x=0
in your graph , when x=0 , y=0 as well

Answer 34

oh, ook
