Statements

1. Angle 1 & angle 2 form a linear pair

2. Angle 1 is supplementary to angle 2

State the two reasons.

I really don't understand this question and I have a test tomorrow

So a supplementary pair of angles would combine to form 180 degrees on the same line however linear pairs are two separate angles that don't have to be touching to form 180 degrees if combined. So it's like all linear pairs are supplementary angles but not all supplementary angles.
