Let \"x\"= the number of miles run on a particular day
\n" ); document.write( "Let \"y\"= the day of the week with Moday = 0, tuesday = 1, etc.
\n" ); document.write( "If I try to make a plot of (x,y) points on a graph,
\n" ); document.write( "I have the points
\n" ); document.write( "{2,0)
\n" ); document.write( "(3,2)
\n" ); document.write( "(4,4)
\n" ); document.write( "Now I have to see what kind of curve goes through
\n" ); document.write( "these points. Hopefully, it's a straight line
\n" ); document.write( "The point-slope formula using the outside points is:
\n" ); document.write( "\"%284+-+0%29%2F%284+-+2%29+=+m\"
\n" ); document.write( "\"m+=+2\"
\n" ); document.write( "The equation would be
\n" ); document.write( "\"%28y+-+0%29%2F%28x+-+2%29+=+2\"
\n" ); document.write( "\"y+=+2%2A%28x+-+2%29\"
\n" ); document.write( "\"y+=+2x+-+4\"
\n" ); document.write( "Does this equation contain the point (3,2)?
\n" ); document.write( "\"2+=+2%2A3+-+4\"
\n" ); document.write( "\"2+=+6+-+4\"
\n" ); document.write( "\"2+=+2\" yes
\n" ); document.write( "So, \"y+=+2x+-+4\" is the equation
\n" ); document.write( "
\n" );
