What are the intercepts from x + y = 56?
\n" ); document.write( "x-int: Let y=0. Then x = 56
\n" ); document.write( "y-int: Let x=0. Then y = 56
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "What are the intercepts from 3y + x = 56?
\n" ); document.write( "x-int: Let y=0. Then x = 56
\n" ); document.write( "y-int: Let x=0. Then 56/3
\n" ); document.write( "------------------------------
\n" ); document.write( "Where would the lines intersect on a graph?
\n" ); document.write( "y = -x+56
\n" ); document.write( "y = (-1/3)x+(56/3)
\n" ); document.write( "-------------
\n" ); document.write( "Solve for \"x\":
\n" ); document.write( "-x+56 = (-1/3)x+(56/3)
\n" ); document.write( "-3x+168 = -x+56
\n" ); document.write( "2x = 112
\n" ); document.write( "x = 56
\n" ); document.write( "If x = 56, y = 0
