Complete the ordered pairs for the equation y = 7x + 21.
\n" ); document.write( "
\n" ); document.write( "( , 0), (2/7, ), (0, ), (-2/7, )
\n" ); document.write( "Ordered pairs are in alphabetical order (x,y)
\n" ); document.write( "For ( ,0), let y=0 and solve for x:
\n" ); document.write( "0=7x+21
\n" ); document.write( "0-21=7x+21-21
\n" ); document.write( "-21=7x
\n" ); document.write( "-21/7=7x/7
\n" ); document.write( "-3=x The ordered pair is (x,y)=(-3,0)
\n" ); document.write( ":
\n" ); document.write( "for (2/7, ) let x=2/7 and solve for y
\n" ); document.write( "y=7(2/7)+21
\n" ); document.write( "y=2+21
\n" ); document.write( "y=23 The ordered pair is (x,y)=(2/7,23)
\n" ); document.write( ":
\n" ); document.write( "for (0, ) let x=0 and solve for y
\n" ); document.write( "y=7(0)+21
\n" ); document.write( "y=0+21
\n" ); document.write( "y=21 the ordered pair (x,y)=(0,21)
\n" ); document.write( ":
\n" ); document.write( "for (-2/7, ) let x=-2/7 and solve for y
\n" ); document.write( "y=7(-2/7)+21
\n" ); document.write( "y=-2+21
\n" ); document.write( "y=19 The ordered pair (x,y)=(-2/7,19)
