Answer

if this is typed correctly, then A. B. C. & D. would all be linear equations.

Step-by-step explanation:

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1    for each of its variables. In this case, the degree of variable y is 1     and the degree of variable x is 1. Therefore, These are all linear equations.
