This is pretty open-ended. How about:

$\sqrt 2$ and $\sqrt 3$ are similar because they're both irrational, meaning neither is the ratio of two integers.

$\sqrt 2$ and $\sqrt 3$ are different because $\sqrt{2} < 1.5}$ and $\sqrt{3} > 1.5$ .

Answer:

General Equation of a Line

$General Equation \\(y - y_{1} )= m (x-x_{1}) \\Slope=m= \frac{x_{2}-x_{1} }{y_{2}-y_{1} } \\\\Given:\\p_{1}=(7,-4)\\p_{2}=(-1,2)\\Solution:\\m=(\frac{-1-7}{2-(-4)}) =\frac{-8}{6}\\y-(-4) = (\frac{-8}{6} )(x-7)\\y+4=\frac{-8x}{6} + 56\\y=\frac{-8x}{6} + 52 \\\\The\\ equation \\ is \\ y=\frac{-8x}{6} + 52$
