(1,7),(3,3)\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=(3-(7))/(3-(1))\r
\n" ); document.write( "\n" ); document.write( "Multiply -1 by the 1 inside the parentheses.
\n" ); document.write( "m=(3-(7))/(3-1)\r
\n" ); document.write( "\n" ); document.write( "Subtract 1 from 3 to get 2.
\n" ); document.write( "m=(3-(7))/(2)\r
\n" ); document.write( "\n" ); document.write( "Multiply -1 by the 7 inside the parentheses.
\n" ); document.write( "m=(3-7)/(2)\r
\n" ); document.write( "\n" ); document.write( "Subtract 7 from 3 to get -4.
\n" ); document.write( "m=(-4)/(2)\r
\n" ); document.write( "\n" ); document.write( "Reduce the expression (4)/(2) by removing a factor of 2 from the numerator and denominator.
\n" ); document.write( "m=-(2)\r
\n" ); document.write( "\n" ); document.write( "Multiply -1 by the 2 inside the parentheses.
\n" ); document.write( "Answer: m=-2 \n" ); document.write( "
