is a linear combination of 
and 
if there are two scalars 
such as
but there are only two possible components for the linear combination. This indicates that only two conditions can be used to determine both scalars, and the other condition must be satisfied once the scalars are found.
and 
, so the solution is
Determine
whether b can be written as a linear
combination of a1 and a2. in other words,...
