So i'm going to make a coordinate 032, where 0 represents my celsius and 32 represents my fahrenheit.
00:09
The other coordinate that i can make is when the temperature is 100 degrees celsius, it tells us that the fahrenheit is 212 degrees.
00:20
All right now, the first part is to find the rate of change of fahrenheit.
00:24
So our equation for rate of change is y2 minus y1 over x2 minus x1.
00:31
So i'm going to plug in my y values.
00:35
So my y2 is going to be 212 minus my y1, which is 32.
00:42
And those are coming from here and here.
00:48
All right.
00:49
And then all divided by my x is the 100 is with the 212 minus 0, which was with the 32.
01:00
So simplifying that, subtracting 212, minus 212, which was with the 32.
01:04
32 that gives me 180 100 minus 0 is still 100 then dividing 180 by a 100 gives me 1 .8 for my rate of change so now i can create my function of c f of c with my slope being 1 .8 all right c for celsius since that is my input value and then plus, we actually know our y intercept from this coordinate here.
01:44
All right...
