document.write( "Question 905664: Biologists have noticed that the chirping of crickets of a certain species is related to temperature, and the relationship appears to be very nearly linear. A cricket produces 113 chirps per minute at 73 degrees Fahrenheit and 172 chirps per minute at 87 degrees Fahrenheit. \r

\"+T+=+f%28+N+%29+\"
\n" ); document.write( "Plot Temp on the vertical axis
\n" ); document.write( "Plot Number of chirps on horizontal axis
\n" ); document.write( "The given points are:
\n" ); document.write( "( 113, 73 )
\n" ); document.write( "( 172, 87 )
\n" ); document.write( "Use the general point-slope formula
