Question 53829: A baby weighs 9 pounds at birth and gained weight at a constant rate of 1/2 pound each week for the first 12 weeks of life. On a graph put baby's weight at the end of each week on y axis and baby's age in weeks on the x axis. How do I find the slope of the line segment between baby's weight at birth and her weight at 12 weeks?

The slope is 1/2. Slope is always the change in "y"
when "x" changes one. Your "y" is total weight;
your "x" is the 1/2 lb. gained in one week. Your
"total weight" value goes up 1/2 lb. for every one-
week change..
