A temperature of 10 degrees corresponds to a temperature of 50 degrees. Also 40 degrees corresponds to 104 degrees. Find the linear equation relating F and C.
\n" ); document.write( ".
\n" ); document.write( "You are given two points:
\n" ); document.write( "(10,50)
\n" ); document.write( "(40,104)
\n" ); document.write( ".
\n" ); document.write( "Slope:
\n" ); document.write( "(y2-y1)/(x2-x1)
\n" ); document.write( "= (104-50)/(40-10)
\n" ); document.write( "= 54/30
\n" ); document.write( "= 27/15
\n" ); document.write( "= 9/5
\n" ); document.write( ".
\n" ); document.write( "Use one of the two points say (10,50) and the slope (9/5) and plug it into the \"point-slope\" form:
\n" ); document.write( "y - y1 = m(x - x1)
\n" ); document.write( "y - 50 = (9/5)(x - 10)
\n" ); document.write( "y - 50 = (9/5)x - (9/5)10
