\n" ); document.write( "y = 5 + 1.5(x-1) = 1.5x + 3.5

\n" ); document.write( "(3,8)
\n" ); document.write( "(4,9.5)
\n" ); document.write( "(5,11)
\n" ); document.write( "========================
\n" ); document.write( "The relation is a function because each domain value has one cast associated with it.
