Algebra.Com's Answer #509221 by pmesler(52)![]() ![]() You can put this solution on YOUR website! To find the slope of a line given two points you use the formula \r \n" ); document.write( "\n" ); document.write( "m = y2-y1/x2-x1.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So, given the points A(8,2) and B(4,1) we will say that 8 = x1 and 2 = y1\r \n" ); document.write( "\n" ); document.write( "4 = x2 and 1 = y2.\r \n" ); document.write( "\n" ); document.write( "Then all you do is plug in the values for the formula and you will find the slope.\r \n" ); document.write( "\n" ); document.write( "m = 1-2/4-8 = -1/-4 = 1/4\r \n" ); document.write( "\n" ); document.write( "Therefore the slope is 1/4. \r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
