\n" ); document.write( "COMPLETE THE ORDERED PAIRS FOR THE EQUATION Y=7X+21
\n" ); document.write( "( ,0),(2/7, ),(0, ),(-2/7, )
\n" ); document.write( "EACH BRACKET IS MISSING A NUMBER.
\n" ); document.write( "Remember that ordered pairs are in this 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 coordinate is: (-3,0)
\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=14/7+21
\n" ); document.write( "y=2+21
\n" ); document.write( "y=23 The coordinate is (2/7,23)
\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 coordinate is: (0,21)
\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=-14/7+21
\n" ); document.write( "y=-2+21
\n" ); document.write( "y=19 The coordinate is (-2/7,19)
