How do you determine if an interval is continuous?
A 1-dimensional interval (a, b) is continuous if for any k in (0, 1) the point a + k*(b-a) = a*(1-k) + k*b is also in the interval. This is equivalent to the statement that every point on the line joining a and b is in the interval. The above can be extended to more dimensions analogously.

How do you apply the comma number format with decimal places?

What is a line-scale and what does it look like?
A line scale is a long line with regularly interval numbers. They are usually used on maps to show distance. They can have different scales (km, cm, in) and compare distances. For example, if you have a map of Canada in a textbook, a line scale in the bottom mights show that every five cm on a page represents 700km on the map.
