By inspection, the first equation, y = -5 is a straight line parallel to the x axis. \n" ); document.write( "That is, for every value of 'x', the value of 'y' is -5. \n" ); document.write( ". \n" ); document.write( "5x + 4y = -20 \n" ); document.write( "rearranging \n" ); document.write( "4y = -5x -20 \n" ); document.write( "y = -5/4x - 5 \n" ); document.write( "which will be a straight line sloping down from the upper left to the lower right, y intercept will be (0, -5); and when x=-4, it will cross the x axis at (-4, 0) \n" ); document.write( ". \n" ); document.write( " |
