A′B′ is half the length of AB.

A′B′ is greater than twice the length of AB.

A′B′ and AB are equal in length.

A′B′ and AB are perpendicular.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

first one because it can't have a fraction in it
