(2,1),(6,9)\r
\n" ); document.write( "\n" ); document.write( "Slope is equal to the change in y over the change in x, or 'rise over run'.
\n" ); document.write( "m=(change in y)/(change in x)\r
\n" ); document.write( "\n" ); document.write( "The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).
\n" ); document.write( "m=(y2-y1)/(x2-x1)\r
\n" ); document.write( "\n" ); document.write( "Substitute in the values of x and y into the equation to find the slope.
\n" ); document.write( "m=(9-(1))/(6-(2))\r
\n" ); document.write( "\n" ); document.write( "Multiply -1 by the 2 inside the parentheses.
\n" ); document.write( "m=(9-(1))/(6-2)\r
\n" ); document.write( "\n" ); document.write( "Subtract 2 from 6 to get 4.
\n" ); document.write( "m=(9-(1))/(4)\r
\n" ); document.write( "\n" ); document.write( "Multiply -1 by the 1 inside the parentheses.
\n" ); document.write( "m=(9-1)/(4)\r
\n" ); document.write( "\n" ); document.write( "Subtract 1 from 9 to get 8.
\n" ); document.write( "m=(8)/(4)\r
\n" ); document.write( "\n" ); document.write( "Reduce the expression (8)/(4) by removing a factor of 4 from the numerator and denominator.
