Best ResponseYou've already chosen the best response.1well, I would treat years as the x variable and population as the y variable, then write an equation using two points from the table I'll pick the first and last point (2009,78) and (2013,93) then write an equation in y = mx + b form

Best ResponseYou've already chosen the best response.0I got 1920 and 1936 and when I didvided got 1.00833so on. I don't think I did it right

Best ResponseYou've already chosen the best response.1remember, slope = (y2y1)/(x2x1) (9378) = ?

Best ResponseYou've already chosen the best response.0I was doing 9373 okay I'm about to do it all over

Best ResponseYou've already chosen the best response.0I mean I was doing 93 minus 2013 okay about to work it all out again

Best ResponseYou've already chosen the best response.0okay I got 3.75 for slope, than I have to work out to get y intercept

Best ResponseYou've already chosen the best response.0ok my slope is 3.75, then I said yy1=m(xx1) so it was y78=3.752009 which i got + 78 to 2009= 1931

Best ResponseYou've already chosen the best response.1ah, I think you've mixed up the equation a bit, let me lend you a hand ^ ^ y78 = 3.75(x2009) start by distributing the 3.75

Best ResponseYou've already chosen the best response.0y78=3.75x7533.75 y78+78=3.75x +787533.75 y=3.75x7455.75 3.75x/7455.75

Best ResponseYou've already chosen the best response.1you can stop here y=3.75x7455.75 this is the equation we need, now plug in x = 2030

Best ResponseYou've already chosen the best response.0ok so 3.75 times 2030. if so that =7612.5

Best ResponseYou've already chosen the best response.1uh, not quite... we're looking for the value of y 3.75*(2030)  7455.75

Best ResponseYou've already chosen the best response.0I meant 7612.57455.75

Best ResponseYou've already chosen the best response.1ok, now subtract those two values

Best ResponseYou've already chosen the best response.1good, now we multiply by 1000 to get 156,750 which means that A is the answer that best approximates the population in 2030
