If 2 angles are adjacent, can it also be said they form a linear pair? Why?

Yes they can. They are two angles next to each other that share the same side that will add up to 180 degrees. For instance, angles of measurements 45 degrees and 135 degrees are together and form a straight line making them both adjacent and forming a linear pair.
However, this does not mean that it can always be said that they form a linear pair.
Consider ABC adjacent to CBD where both are 20 degrees. They are adjacent, but do not form a linear pair, because they are not supplementary.
