On a certain day, the temperature was 37 Fahrenheit at 10am and 49 fahrenheit at 1pm. if the temperature rose at a constant rate from 10am to 1pm on that day, what was the temperature at 11am?
\n" ); document.write( "

Let x be time, with starting time being x = 0. Then y is the temperature at a particular time of the day
\n" );
document.write( "We then get: 
\n" );
document.write( "Points: (0, 37) and (3, 49)
\n" );
document.write( "Slope or m = , or m = 4

document.write( ", or  -------- Equation representing temperature at a certain time of the day
\n" );
document.write( "Since 11am is the 1st hour, or hour 1 after 10am, then  becomes: , or .
\n" );
document.write( "Therefore, temperature, 1 hour after 10am, or at 11am =  \n" );
document.write( "

\n" );
