Answer:
Let the matrix associated to the system and
the vector of constant values of the system.
The equation of the line joining p and q is
. Since p and q are solutions of the linear system then,
and
Let . Observe that
. Then w is a solution of the homogeneous system Ax=0.
Now, let s=p+r(q-p) for some be a point in the line joining p and q. Observe that
Then As=b. This means that s is a solution of the linear system.
