Answer:
the linear equation is :
y= -2625x+5737875
and 440000 employees will be in year 2271
Step-by-step explanation:
in order to find the linerar equation let us first convert the given data into (x,y ) co-ordinates i.e
x1= 1987 y1= 522,000
and
x2= 2003, y2 = 480000
according to two point form:
In this example we have x1=1987 , y1=522000 , x2=2003 and y2=480000. So,
now to find the year when there will be 440000 employs working , we simply put y= 440000 in the above derived equation
