There is a linear correlation, but the origin is not at 0.

Both scales have a constant linearity to them, and 1 degree Celsius increase is always a 1.8 degree Farenheit increase.

This graph plots one against the other, as you can see showing a linear correlation. https://d1uvxqwmcz8fl1.cloudfront.net/tes/resources/11829524/ff0efc69-c7a4-4963-ba86-c733ac6602a3/image?width=500&height=500&version=1541452521288

This is a very nice example.

You can also tell from the conversion formula (which is the formula behind that graph, too) that the relationship is linear. Namely...

>F = 1.8 * C + 32 (or C = 5/9 * F - 32)

...is a classic a * x + b linear formula.

E: switched F and C originally.

Actually, it's F = 1.8 * C + 32

Cool, now I am confused.

I described the conversion of celsius to fahrenheit but accidentally flipped the F and C in the formula. It's corrected now, and I added the opposite conversion for good measure.

Oh yes, I switched them up. Lemme fix that.
