Taking years as input variable and population of that city as output variable, let y represent the population after 1985 and y represent the population in and index of 1000. Linear regression is a modeling relationship that exists between the variable. 
The equation, therefore, can be derived in Y=a+bX. In this case, Y is the independent variable that is drawn on the axis of the graph while X represents the variable plotted on the x-axis of the graph; finally, b is line slope.
