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
