What is a \(y\)-intercept of a graph?
$$\text { Simplify: } \quad 3\left(12 \div 2^{2}-3\right)^{2}$$.
The graph shows that in \(2000,31 \%\) of U.S. adults viewed a college education as essential for success. For the period from 2000 through 2010 , the percentage viewing a college cducation as essential for success increased on average by approximately 2.4 each year. These conditions can be described by the mathematical model $$ S=2.4 n+31 $$ where \(S\) is the percentage of U.S. adults who vicwed college as essential for success \(n\) years after 2000 . a. Let \(n=0,5,10,15,\) and \(20 .\) Make a table of values showing five solutions of the equation. b. Graph the formula in a rectangular coordinate system. Suggestion: Let each tick mark on the horizontal axis, labeled \(n,\) represent 5 units. Extend the horizontal axis to include \(n=25 .\) Let each tick mark on the vertical axis, labeled \(S\), represent 10 units and extend the axis to include \(S=100\)
