You can put this solution on YOUR website!
find the missing coordinate in the solutions for 3x-y+=-7\r
\n" ); document.write( "\n" ); document.write( "a. (?, 7)
\n" ); document.write( "If y=7 you get 3x-7=-7; 3x=0; x=0
\n" ); document.write( "---------------
\n" ); document.write( " B. (2, ?)
\n" ); document.write( "If x=2 you get 3*2-y=-7; y=6+7; y=13
\n" ); document.write( "-----------------
\n" ); document.write( "another problem I have is\r
\n" ); document.write( "\n" ); document.write( "4x + y =5 by plotting points I need at least three
\n" ); document.write( "If x=0, y=5
\n" ); document.write( "If y=0,x=5/4
\n" ); document.write( "if x=-1, y=9
\n" ); document.write( "==================
