Question

The graph (in comments) gives the data points from an experiment involving oxygen and hydrogen. Which of the following best approximates the equation, with oxygen as a function of hydrogen: O=mH+b
A. O = .625 H + 0.75
B. O = 1.6 H - 1.2
C. O = .625 H - 1.2
D. O = 4.0 H + 4.2
E. none of these

Answer 1

@KendrickLamar2014 can you help me?

Answer 2

ill do my best

Answer 3

okay thank you <3

Answer 4

Its either B or E

Answer 5

alright how do i figure out which one?

Answer 6

Give me a sec...

Answer 7

okay!

Answer 8

okay..

Answer 9

its okay thank you!

Answer 10

@jigglypuff314

Answer 11

it is in the form y = mx +b
where m = slope and b = y-intercept
can you estimate about what is the slope and y-intercept of the given graph? :)

Answer 12

sure give me a second :)

Answer 13

1/3 is slope?

Answer 14

im a bit confused on this graph.

Answer 15

mmm try using points (1,1) and (3,4) to find the slope

Answer 16

is it 3/2

Answer 17

yes. and that is just an estimate
but from this we can tell that the slope is supposed to be more than but close to 1

Answer 18

okay

Answer 19

from the options given
A. O = .625 H + 0.75
B. O = 1.6 H - 1.2
C. O = .625 H - 1.2
D. O = 4.0 H + 4.2
can you tell which equation has the slope that is more than but close to 1 ?

Answer 20

A?

Answer 21

actually let me do the math quickly. one second instead of guessing.

Answer 22

okay so A?

Answer 23

more than but close to 1
^
is 0.625 more than 1? :P

Answer 24

ohh i thought added together more than but close to 1. then the answer would be B.

Answer 25

yes ^_^
