Question 941098: Water Freezes at 0 Celsius and 32 Farenheit. Water boils at 100 C and 212 F.
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).
B. Use the equation to find F for C=16. Use the equation to find C for F=100.
C. At what temperature are farenheit and celsius the same (where does F=C)?

Water Freezes at 0 Celsius and 32 Farenheit. Water boils at 100 C and 212 F.
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).
:
Use the slope formula: m =
Assign the x,y points as follows,
x1=0; y1=32
x2=100; y2=212
Find the slope (m)
m = = =
y = mx + b, the slope intercept equation
When x=0, y=32, therefore b = 32
y = x + 32; is the equation
:
B. Use the equation to find F for C=16.
y = (16) + 32
y = 28.8 + 32
y = 60.8 degrees Farenheit
Use the equation to find C for F=100.
x + 32 = 100
x = 100 - 32
x = 68
x = 68
x = 37.78 Celsius
;
C. At what temperature are Fahrenheit and Celsius the same (where does F=C)?
write the equation
y = y + 32
y - y = 32
y = 32
y = (32)
y = -40 degrees, F & C are the same
