Water Freezes at 0 Celsius and 32 Farenheit. Water boils at 100 C and 212 F.
\n" ); document.write( "A. Find the equation of the line that relates F to C. Use F=Y and C=X and you were given two points on the line, the first point is (0,32).
\n" ); document.write( ":
\n" ); document.write( "Use the slope formula: m = \"%28%28y2-y1%29%29%2F%28%28x2-x1%29%29\"
\n" ); document.write( "Assign the x,y points as follows,
\n" ); document.write( "x1=0; y1=32
\n" ); document.write( "x2=100; y2=212
\n" ); document.write( "Find the slope (m)
\n" ); document.write( "m = \"%28%28212-32%29%29%2F%28%28100-0%29%29\" = \"180%2F100\" = \"9%2F5\"
\n" ); document.write( "y = mx + b, the slope intercept equation
\n" ); document.write( "When x=0, y=32, therefore b = 32
\n" ); document.write( "y = \"9%2F5\"x + 32; is the equation
\n" ); document.write( ":
\n" ); document.write( "B. Use the equation to find F for C=16.
\n" ); document.write( "y = \"9%2F5\"(16) + 32
\n" ); document.write( "y = 28.8 + 32
\n" ); document.write( "y = 60.8 degrees Farenheit
\n" ); document.write( "Use the equation to find C for F=100.
\n" ); document.write( "\"9%2F5\"x + 32 = 100
\n" ); document.write( "\"9%2F5\"x = 100 - 32
\n" ); document.write( "\"9%2F5\"x = 68
\n" ); document.write( "x = \"5%2F9\"68
\n" ); document.write( "x = 37.78 Celsius
\n" ); document.write( ";
\n" ); document.write( "C. At what temperature are Fahrenheit and Celsius the same (where does F=C)?
\n" ); document.write( "write the equation
\n" ); document.write( "y = \"9%2F5\"y + 32
\n" ); document.write( "y - \"9%2F5\"y = 32
\n" ); document.write( "\"-4%2F5\"y = 32
\n" ); document.write( "y = \"-5%2F4\"(32)
\n" ); document.write( "y = -40 degrees, F & C are the same
\n" ); document.write( "
\n" ); document.write( "
