Question 285659: Life Span Some scientists believe there is a limit to how
long humans can live.* One supporting argument is that
during the last century, life expectancy from age 65 has
increased more slowly than life expectancy from birth, so
eventually these two will be equal, at which point, according
to these scientists, life expectancy should increase no
further. In 1900, life expectancy at birth was 46 yr, and life
expectancy at age 65 was 76. In 2000, these figures had
risen to 76.9 and 82.9, respectively. In both cases, the
increase in life expectancy has been linear. Using these
assumptions and the data given, find the maximum life
expectancy for humans.

Question 285718: I am working on systems of linear equations.
(Solve the system by graphing
my book says to use the y-intercept and the slope to graph each line.
The equations are: y = x-3 and y = x+1 I got a intersect at (2, 0)
When I do a check I do not believe that this satisfies both equation.
Can you detail out step by step instruction on how to solve this problem.
I might be getting the y-intercept and the slope information data wrong. I am just not sure.
Thank you.
