1. The distance from a point [unparseable or potentially dangerous latex formula] to a line [unparseable or potentially dangerous latex formula] is given by the equation

[unparseable or potentially dangerous latex formula]

Plugging in the values, we have

[unparseable or potentially dangerous latex formula]

2. [unparseable or potentially dangerous latex formula]

4. The centroid is the average of the [unparseable or potentially dangerous latex formula] and [unparseable or potentially dangerous latex formula] values.

So, [unparseable or potentially dangerous latex formula]
