Concept explainers
In 2007, the U.S. government faced the prospect of paying out more and more in social security, Medicare, and Medicaid benefits. The line graphs shows the costs of these of these entitlement programs, in billions of dollars, from 2007 through 2016 (projected).Use this information to solve Exercises 71 – 72on the page.
Cost in Billions of dollars of the Largest Federal Entitlement Programs
(In Exercises 71–72 refer to the graphs at the bottom of the previous page.)
a. Find the slope of the line segment representing social security. Round to one decimal place. Describe what this means in terms of rate of change.
b. Find the slope of the line segment representing Medicaid. Round to one decimal place. Describe what this means in terms in of rate of change.
c. Do the line segments for social security and Medicaid lines? What this in terms of the rate of change for these for these entitlement programs?

Remember that: A matrix is in row echelon form if Any row that consists only of zeros is at the bottom of the matrix. The first non-zero entry in each other row is 1. This entry is called aleading 1. The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.arrow_forward
