Answer 9

\[y=50x+1200\]assuming 2005 is year 0

Answer 10

but what do i write for part b

Answer 11

that one up there

Answer 12

yes

Answer 13

Answer 14

I'm really confused what to write @saseal

Answer 15

since he started business in 2005 so year 0 is x=0

Answer 16

thats the equation is slope intercept form?

Answer 17

when year 0 his price is 1200 that is the y-intercept

Answer 18

yup

Answer 19

x=0?

Answer 20

x=0 then y=1200

Answer 21

try x=3 see if you get 1350

Answer 22

im confused

Answer 23

with?

Answer 24

how to get the equation

Answer 25

you learned y=mx+c ?

Answer 26

i did y=mx+b

Answer 27

thats the equation for slope right?

Answer 28

its the same thing

Answer 29

yea

Answer 30

ok

Answer 31

thats what they want you to do

Answer 32

so whats the final answer?

Answer 33

@saseal ^

Answer 34

is it y=50x+3? @saseal

Answer 35

y=50x+1200

Answer 36

can u help me with another? @saseal
