The population of a small town in 1990 was 1,200 people, and the population in 2000 was 2,700 people. Let x represent the number of years since 1990. Let y represent the population. Which linear equation represents this data?
well... looking at how to question is defining things.....i think this is a multiple choice question.....
Given: "y" represents the population "x" represents the number of years duration = 2000 - 1990 = 10 years population increase = 2700 - 1200 = 1500 Now, It says linear equation........, So, we have to assume that every ten years the population increases by a fixed amount that is 1500 people every 10 years.
Now, Every 10 years, the population increases by 1500 Every 1 year , the population increases by 1500 / 10 = 150
Now, The equation in determining the population is:
