equation is y - 4.2 = 3.5 * (x - 2)
\n" ); document.write( "add 4.2 to both sides of the equation to get:
\n" ); document.write( "y = 3.5 * (x - 2) + 4.2
\n" ); document.write( "i think selection C.
\n" ); document.write( "that is minus infinity <= x <= plus infinity.
\n" ); document.write( "this means any real value of x can be used as input to the function and that the result will be a real value of y for each and every value of x.\r
