I understand that the following is a linear combination of vectors $y_{1},..., y_{n}$:
$a_{1}y_{1} + a_{2}y_{2} + ... + a_{n}y_{n}$
My doubt is whether, the following which has an additional constant term $a_{0}$, can also be called a linear combination of vectors $y_{1},..., y_{n}$:
$a_{0} + a_{1}y_{1} + a_{2}y_{2} + ... + a_{n}y_{n}$
