50°F. Also 40°C corresponds to 104°F. Find the linear equation relating F and C.

Consider this as two ordered pairs, (10, 50) and (40, 104), with C as x and F as y. The slope is (104 - 50)/(40 - 10) = 9/5 = 1.8, so the equation is y = 1.8x + b, where you still don't know b. Use the first point to see that 50 = 1.8*10 + b ==> b = 50 - 18 = 32. So y = 1.8x + 32, or F = 1.8C + 32. This is easy to verify as correct, because it is a well known conversion formula. You may already know it by heart, but I'm assuming you were required to show your work.

F=9/5 C +32
C=F-32(5/9)

Tc = (5/9)*(Tf-32); Tc = temperature in degrees Celsius, Tf = temperature in degrees Fahrenheit

Here's a rule of thumb to convert temp. from C to F. Double it and add 30. Therefore 10 becomes 20+30=50F. Or thereabouts.

(F-32) * 5 / 9=C
