Which of the ordered pairs
\n" ); document.write( " (–7, 2), (1, 0), (–3, –1), (–23, 6)
\n" ); document.write( ":
\n" ); document.write( "are solutions for the equation x + 4y = 1?
\n" ); document.write( ":
\n" ); document.write( "Each ordered pair represents the values of x & y.
\n" ); document.write( ":
\n" ); document.write( "Substitute the values for x & y and see if the equation is true;
\n" ); document.write( ":
\n" ); document.write( "The first pair: (-7,2), substitute these value for x & y in x + 4y = 1
\n" ); document.write( ":
\n" ); document.write( " -7 + 4(2) =
\n" ); document.write( " -7 + 8 = 1, so the 1st pair is a solution
\n" ); document.write( ":
\n" ); document.write( "The 2nd pair: (1,0)
\n" ); document.write( ":
\n" ); document.write( " 1 + 4(0) = 1
\n" ); document.write( " 1 + 0 = 1 so the 2nd pair is also a solution
\n" ); document.write( ":
\n" ); document.write( "The 3d pair: (-3,-1)
\n" ); document.write( ":
\n" ); document.write( " -3 + 4(-1) = 1
\n" ); document.write( " -3 - 4 = -7 so this is not a solution
\n" ); document.write( ":
\n" ); document.write( "The 4th pair: (-23,6)
\n" ); document.write( ": -23 + 4(6) = 1
\n" ); document.write( " -23 + 24 = 1 so this is a solution also
\n" ); document.write( " \n" ); document.write( "
\n" );
