Which of the ordered pairs
\n" ); document.write( "(0, 0), (–2, 10), (–1, –5), (–3, 9)
\n" ); document.write( "are solutions for the equation y = 5x?
\n" ); document.write( ":
\n" ); document.write( "This is so easy. You know that the 1st digit in the pair is x and the 2nd is y:
\n" ); document.write( ":
\n" ); document.write( "y = 5x
\n" ); document.write( "Substitute the value of x for x and see if it equals y
\n" ); document.write( ":
\n" ); document.write( "(0,0)
\n" ); document.write( "y = 5*0
\n" ); document.write( "y = 0 so this is a solution:
\n" ); document.write( ":
\n" ); document.write( "(-2,10)
\n" ); document.write( "y = 5*-2
\n" ); document.write( "y = -10; this is not a solution
\n" ); document.write( ":
\n" ); document.write( "(-1,-5)
\n" ); document.write( "y = 5*-1
\n" ); document.write( "y = -5; this is a solution
\n" ); document.write( ":
\n" ); document.write( "(-3,9)
\n" ); document.write( "y = 5*-3
\n" ); document.write( "y = -15; this is not a solution
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Do you understand this now? Any questions?
\n" ); document.write( " \n" ); document.write( "
\n" );
