Slope is defined as the change in the vertical distance divided by the corresponding
\n" ); document.write( "change in the horizontal distance. In this problem the change in the vertical distance is
\n" ); document.write( "+ 8.5 ft and the corresponding change in the horizontal distance is 18.02 ft. So the slope
\n" ); document.write( "of the roof is:
\n" ); document.write( ".
\n" ); document.write( " $\"slope+=+8.5%2F18.02\"$
\n" ); document.write( ".
\n" ); document.write( "and doing the division with a calculator gives you:
\n" ); document.write( ".
\n" ); document.write( " $\"slope+=+0.471698113\"$
\n" ); document.write( ".
\n" ); document.write( "Rounding this to the nearest hundredth tells you to look at the third position to the right of
\n" ); document.write( "the decimal point. It is a 1. Since that is less than 5, you leave the second position
\n" ); document.write( "to the right of the decimal point at the value it is. So the rounded answer is:
\n" ); document.write( ".
\n" ); document.write( " $\"x+=+0.47\"$
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to understand the meaning of slope.
