a) t=T-273 musta suora
b) Tunnetut pisteet (0C, 32F) ja (100C, 212F) sininen suora

\text{kulmakerroin} \
k=\frac{\Delta y}{\Delta x}=\frac{212-32}{100-0}=\frac{9}{5} \
\Rightarrow F-212=\frac{9}{5}(t-100) \
\Rightarrow F=\frac{9}{5}t+32

f: y = x - 273
A = Intersect(yAxis, f)
B = Intersect(xAxis, f)
g: y = (9 / 5 * x) + 32
