Step-by-step explanation:
The complete question is:
In 1960, there were 237,794 immigrants admitted to a country. In 2001, the number was 1,150,729.
a. Assuming that the change in immigration is linear, write an equation expressing the number of immigrants, y, in terms of t, the number of years after 1900.
b. Use your result in part a to predict the number of immigrants admitted to the country in 2013.
c. Considering the value of the y-intercept in your answer to part a, discuss the validity of using this equation to model the number of immigrants throughout the entire 20th century.
Answer:
a) From the question, we can get two ordered pairs which are
Using the equation of a line given two points:
b) In 2013, t = 2013 - 1900 = 113.
Hence:
c)
Since the y intercept is negative, that is in 1900 the number of immigrants was -1098206 which can not be possible. Hence this equation is not valid and the growth may or may not be linear.
