23,000+.02x=y. You have to add 2% or .02 times the number of years(x) to 23,000 to get the populatin(y) from 2012
The area for this is 48.
Hope this is helpful!
You are given two points on the line:
.. (1, 7) and (4, 5.5)
You can use the 2-point form of the equation for a line.
.. y = (y2-y1)/(x2-x1)*(x -x1) +y1
.. y = (5.5 -7)/(4 -1)*(x -1) +7
.. y = -0.5x +7.5
Your linear equation is y = -0.5x +7.5
