Species

Species within the genus Pisulina include:

gollark: You could get the same hard-to-brute-force-ness with, apparently, a 37 digit base 10 one.
gollark: It's basically just a convoluted way to express a 60-digit base-4 number.
gollark: The important thing is how much y increases each time x goes up by 1, which is the gradient.
gollark: I think so, yes. Generally I would take the equation (y = 3x + c) and substitute in one of the points' x and y values, but I guess for this that works.
gollark: You have the value when x = 1.
