Algebra.Com's Answer #39344 by phillv(13)![]() ![]() ![]() You can put this solution on YOUR website! Rewrite the equation in the forme of equation for a line: \n" ); document.write( "Y=mX+b where m is the slope or stepeness of the line. \n" ); document.write( "A positive slope indicates that the line will slant up and to the right. \n" ); document.write( "Y=100X+500\r \n" ); document.write( "\n" ); document.write( "Find the Y intercept by setting x=0 \n" ); document.write( "When X=0, Y=500 \n" ); document.write( "The Y intercept is Y=500\r \n" ); document.write( "\n" ); document.write( "Find X intercept when Y=0 \n" ); document.write( "When Y=0, 0=100X+500 \n" ); document.write( "-500=100X, X=-500/100, X=-5 \n" ); document.write( "When Y=0, X=-5 \n" ); document.write( "The X intercept is X=-5\r \n" ); document.write( "\n" ); document.write( "We now know that (0,500)and (-5,0) \n" ); document.write( "are two points of this line. \n" ); document.write( "Plot the two points and draw the line.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
