Algebra.Com's Answer #510951 by swincher4391(1107)![]() ![]() You can put this solution on YOUR website! Slope-intercept form : y = mx+b <-- remember this.\r \n" ); document.write( "\n" ); document.write( "m is our slope. b is our intecept.\r \n" ); document.write( "\n" ); document.write( "You may think of m as move and b as begin, though this is not what they really stand for.\r \n" ); document.write( "\n" ); document.write( "so m = -3 <--- slope (perhaps think of this as -3 / 1]\r \n" ); document.write( "\n" ); document.write( "b = 3 <--- y-intercept.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So I begin at y=3,\r \n" ); document.write( "\n" ); document.write( "Then I move down 3 and right 1 and plot a point. You could connect the dots at this point, but I always do 3 points so instead make a point that goes up 3 and left 1 as well. It should be a downward sloping line that goes through (-1,6), (0,3), (1,0) \n" ); document.write( " |
