Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Question

A nationa! census is mandated by the Constitution of Pakistan to be held every ten
years. After the independence of Pakistan in 1947, the first census took place in 1951.
Figure 1 reflects the increase in population of Pakistan during last four nationa! census.
The increase between 1972 and 2017 could be approximated by a linear function. If in
1972 the popuiation was 65.309 million and as per the census data of 2017 the popuiation
was 207.774 million;
a) Determine the estimation function P = f (t), where P equais the popuiation of Pakistan
and t equals time measured in years since 1972.
b) Interpret the slope and P intercept
c) According to this function, what wii be the estimated popuiation of Pakistan in 2027
census?
