Best ResponseYou've already chosen the best response.2please wait, I'm working on your answer...

Best ResponseYou've already chosen the best response.2I understand. We have to write two functions which model your data contained in both tables

Best ResponseYou've already chosen the best response.2for example, let's consider the first table

Best ResponseYou've already chosen the best response.1Okay so to find m: \[\frac{ (y_2  y_1) }{ (x_2 x_1) }\]

Best ResponseYou've already chosen the best response.2when x=0, we have y=0.8, so we can write: 0.8=m*0+b=b so b=0.8

Best ResponseYou've already chosen the best response.1So i am going to use the coordinates: (1,1) and (2,1.2) \[\frac{ (1.2  1) }{ (2 1 ) }\]

Best ResponseYou've already chosen the best response.2similarly, when x=1, we have y=1 so we can write: 1=m*1+b=m+b=m+0.8 then: m=10.8=0.2 I prefer the substitution method

Best ResponseYou've already chosen the best response.1\[\frac{ 0.2 }{ 1 }\]

Best ResponseYou've already chosen the best response.2ok! so we can write: y=0.2*x+0.8

Best ResponseYou've already chosen the best response.2now we have to do the same, with the second table
