Polls

The first poll allows only one answer.

What is the equation of a line in a plane?

		\(ax^2 + bx + c = 0\)
		\(ax + by + cz + d = 0\)
		\((x-x_0)^2 + (y-y_0)^2 - r^2 = 0\)
		\(ax + by + c = 0\)
		\(y = at^2 + v_0t + y_0\)
		I don't know

The next poll allows multiple selections, doesn't number the answers, has no solutions to show, and auto-closes after 30 seconds.
