Given are x and y values, in the form of the function.
\n" ); document.write( "Therefore,
\n" ); document.write( "f(-4)=5 is (-4, 5)
\n" ); document.write( "f(2) =2 is (2, 2)
\n" ); document.write( "...
\n" ); document.write( "First, find slope
\n" ); document.write( "\"%285-2%29%2F%28-4-2%29+=+3%2F-6+=+%28-1%2F2%29\"
\n" ); document.write( "Second, take slope and one point within the point-slope formula
\n" ); document.write( "y - 5 = \"%28-1%2F2%29%28x--4%29\"
\n" ); document.write( "y - 5 = \"%28-1%2F2%29%28x%2B4%29\"
\n" ); document.write( "y - 5 = \"%28-1%2F2%29x+-+%281%2F2%29%284%29\"
\n" ); document.write( "y - 5 = \"%28-1%2F2%29x+-+2\"
\n" ); document.write( "y = \"%28-1%2F2%29x+-+2+%2B+5\"
\n" ); document.write( "y = \"-1%2F2\"x + 3
\n" ); document.write( "The linear function is then,
\n" ); document.write( "\"highlight_green%28f%28x%29=%28-1%2F2%29x%2B3%29\"
