amistre64 · Answer

you might want to develop the line equation (im assuming they are lines) and see where they cross

amistre64 · Answer

linear regressions then?

dobby1 · Answer

How would i do that.

amistre64 · Answer

i need to know more about the context of the question ... the data is not strictly a line

dobby1 · Answer

My question only gave me the info i gave you

amistre64 · Answer

i know, and the question is part of some class; that class contains material that it covers; and the material that it covers will help me to understand how to proceed.

dobby1 · Answer

My class is algebra 2 this lesson is on solving equations using tables and graphs

amistre64 · Answer

i dont spose youve covered any regression models?

dobby1 · Answer

i dont think so

amistre64 · Answer

my ti83 gives me a few linear regression equations; the rest is to equate them

y = 4100x + 300
y = 1900x+19900

amistre64 · Answer

let x be the month we are looking for

amistre64 · Answer

the other way would be to plot the points and draw rough lines to see where they meet

dobby1 · Answer

which sould you suggest because i am really confused

amistre64 · Answer

plotting lines would be the "simplest" if mathing it is not your speed

dobby1 · Answer

ok but i still dont under stand how I am sapposed to graph them

amistre64 · Answer

plot the points:

1,4000
2,9000
3,13000

etc

draw a rough line to approximate it


then for the other one:  
1,22000
2,24000
3,25000
etc

amistre64 · Answer

maybe a high low estimation of a line to determine a slope with

define the line from (1,4000) to (6,21000)
and
define the line from (1,22000) to (6,30000)

see where they cross
