Answer 1

"write degrees C as a function of degrees F" implies that C should be the dependent variable and F should be independent

Answer 2

in other words, you are treating the degrees C values as y and degrees F as x

Answer 3

so you would find the linear equation between points (32,0) and (212,100) and write this in terms of C and F

Answer 4

@pooja195

Answer 5

@Vocaloid it would depend on each other right

Answer 6

I am not exactly sure what you mean by this

Answer 7

c=fx?

Answer 8

your function should be in terms of C and F only

Answer 9

c=f

Answer 10

good, so it would look something like that, except with a slope/intercept/etc.

Answer 11

if it helps, treat (32,0) and (212,100) as (x,y) points and calculate it as if everything were in x and y

Answer 12

then just replace x and y with F and C

Answer 13

slope is 5/*9

Answer 14

good what about the y-intercept?

Answer 15

um it could be 0 or 100

Answer 16

y = mx + b
0 = (5/9)(32) + b
solve for b

Answer 17

leave it as a fraction

Answer 18

-160/9

Answer 19

awesome so your final eq is C = (5/9)F - (160/9)

Answer 20

wait so this is 3A right

Answer 21

well 3b is 5/9

Answer 22

good, and 5/9 is the rate at which celsius changes per 1 degree change in fahrenheit

Answer 23

and the y-intercept is the temperature in degrees celcius at 0 degrees fahrenheit

Answer 24

I suppose you could also mention that -160/9 is approximately -17.78 degrees celcius since that's more intuitive to the average person

Answer 25

and a is c=f right?

Answer 27

oh so that would be a?

Answer 28

yes

Answer 29

I have to go to class, I'll help you later hopefully ;_;

Answer 30

Sounds good

Answer 31

Good luck
