I need help solving with this graphing symtem of equation?\r \n" ); document.write( "\n" ); document.write( "x+y=9 ...or...y=-x+9...now draw a graph for this taking different values for x and finding corresponding values of y ..ex..when x=0 we get y=0+9=9...etc.. \n" ); document.write( "make a table as follows and draw the graph plotting these points \n" ); document.write( "x...0....1....2....3.....-1.....-2.....-3 \n" ); document.write( "y...9....8....7....6.....10......11.....12 \n" ); document.write( "similarly now do for the next eqn... \n" ); document.write( "2y-x=6...or...2y=x+6...or...y=(x+6)/2 \n" ); document.write( "x...0....1....2....3.....-1.....-2.....-3 \n" ); document.write( "y...3....7/2..4....9/2...5/2....2.....3/2 \n" ); document.write( "draw both graphs in one sheet .find where they cut each other.find the point where they cut each other .the x and y coordinates of that point give us the values of x and y. \n" ); document.write( " \n" ); document.write( "we find that x=4 and y=5 \n" ); document.write( " |
