Storyboard Text

  • Hi, I am trying to figure out how to convert degrees Celsius into degrees Fahrenheit. I can't figure it out.
  • Hey Frank, what are you still doing in the lab? School is over.
  • I'll show you, you see you have to write an equation expressing F(Fahrenheit) in terms of C (Celsius).
  • So What do I do first?
  • First you need to find out m and b, which are m=-1.8, and b= 32. Then once you have M and B you can put the numbers you got for them into an equation. M represents the slope and B represents the Y-intercept.
  • So that would be y=-1.8x + 32.
  • How about you try one, like lead boils at 1620 Celsius, what is the Fahrenheit temperature?
  • So you would start with y=-1.8(1620)+32. Then multiply -1.8 by 1620 to make it y= -2916+ 32. Then you add -2916 and 32 to get -2884.
  • So for my science project I can figure out the human body temperature in Celsius by doing 98.6=-1.8x+32 to get -37.
  • For other situations you might have to transform the equation so that C is in terms of F. So you would have to put the number in the situation as y and solve for x.
  • And for my science project I can figure out what absolute zero is in Fahrenheit instead of -273 Celsius. So I would start with y=-1.8(-273) + 32. I would end up getting -459.4 degrees Fahrenheit. Thanks for teaching me all of this about linear functions!
  • Today the weather man said it will be 40 degrees Celsius but I would rather know in Fahrenheit to understand better. So I can use our original formula by doing y=-1.8(40)+32. Then I change it to y=-72+32 by multiplying -1.8 and 40 to get -72. Then I can do -72+32 to get -40. Now I know to bundle up tomorrow.
