To get to a friend's house from his apartment, a student walks 4 blocks west and 6 blocks south. Usine the origin of a coordinate plane as the starting point,
\n" ); document.write( "Find the coordinates of the locateion of the friends apartment
\n" ); document.write( "How far from the student's apartment is the friend's house?
\n" ); document.write( "--------------------
\n" ); document.write( "West is negative along the x-axis, and South is negative on the y-axis (per conventions), so he walked to the point (-4,-6) (using the blocks as units).
\n" ); document.write( "(-4,-6) are the coordinates.
\n" ); document.write( "The distance he walked was 10 blocks, but the straight line distance is:
\n" ); document.write( " $\"sqrt%284%5E2+%2B+6%5E2%29\"$
\n" ); document.write( "= $\"sqrt%2852%29\"$
\n" ); document.write( "= $\"2sqrt%2813%29\"$
\n" ); document.write( "Which is apx 7.211 blocks \n" ); document.write( "

\n" );
